	2	=== EBRAINS infrastructure causing issues with the Drive ===
146.1	3
149.1	4	The Drive is currently down due to another issue at CSCS. We are working on getting this resolved as soon as possible.
	5
	6	=== EBRAINS infrastructure was down this morning (Fixed) ===
	7
146.1	8	The cloud infrastructure at that hosts most EBRAINS services had at the [[Swiss National Computing Center (CSCS)>>https://cscs.ch]] experienced some downtime this morning from 9:25 to 10:15 CEST. This interrupted access to the storage of most of our services making them unavailable to end users. Service is up again.
	9
	10	We will update this page with more information when we receive information about the root causes.
	11
	12	We apologize to EBRAINS users for the down time. Please [[contact Support>>https://ebrains.eu/support]] if you still experience issues with any service.
	13
145.1	14	=== Drive is currently down (Fixed) ===
142.1	15
143.1	16	The Drive is currently down and not usable. This is due to infrastructure issues and service will be restored as soon as possible.
142.1	17
145.1	18	Update 2022-10-17 21:30 CEST: CSCS and RedHat are still debugging the issue.
143.1	19
145.1	20	2022-10-18: The issue has been resolved and the Drive is now accessible again. The issue was caused by the restart of an Openstack hypervisor with an inconsistent status of volumes in Openstack. This locked the VM running the Collaboratory Drive in a shutoff state. CSCS had been informed of the problem 6 weeks earlier.
144.1	21
141.1	22	=== Unable to save files to Drive (Fixed) ===
139.1	23
	24	The file system that the Drive runs on is currently full. Unfortunately, our detection of the file system being nearly full did not work. As such users cannot upload files nor save any changes to their files in the Drive. Due to another, unrelated issue, it is not possible for us to simply expand the file system. For this reason, we are currently in the process of moving the Drive data to a bigger volume. This is causing the delay. We will update this page as soon as we are finished with the move.
140.1	25	\\Please note that as most services run off the Drive, this also affects the Lab, although you can run Notebooks and even modify notebooks, any changes you make will not be saved.
139.1	26
143.1	27	NOTE: We transferred everything from the affected volume to a larger volume, the service is now usable again.
141.1	28
138.1	29	=== No uploads allowed to Data-proxy (Fixed) ===
135.1	30
138.1	31	At the moment uploads are not permitted due to the data-proxy exceeding its quota allowance. We are working to solve this as soon as possible.
	32	\\Fixed: Quota was increased, files can no be uploaded again.
137.1	33
	34	=== Collaboratory Drive maintenance (2022-08-19) (Completed) ===
	35
136.1	36	The Drive was meant to be taken down for routine maintenance to increase the available space available for Drive storage this afternoon. That operation has had to be rescheduled due to technical issues on the storage infrastructure.
135.1	37
134.1	38	=== Intermittent issues with the Bucket (data-proxy) (Solved) ===
	39
	40	As reported by the main banner, there had been intermittent issues with the Bucket occasionally going down for a short amount of time. This has been resolved by the maintenance performed at CSCS on August 10th. If you encounter any further issues related to the Bucket, please open a ticket to support.
	41
133.1	42	=== Storage and Cloud service maintenance (2022-08-10) (Completed) ===
129.1	43
131.1	44	This maintenance was shifted from August 3 to August 10 due to an incident on another server managed by the ETHZ central IT services.
	45
130.1	46	A maintenance operation at CSCS requires that some HBP/EBRAINS services be stopped Wednesday August 3 morning. The services affected are those using NFS storage volumes on the Castor cloud service. EBRAINS service providers that migrate their VMs to CEPH storage ahead of that date can keep their services running during the maintenance.
129.1	47
130.1	48	__Timeline__: all times CEST
129.1	49
130.1	50	* 08:00: Service providers shutdown services running on OpenStack or OpenShift at CSCS
	51	* 08:30: Maintenance start by CSCS team
	52	* 12:00: Planned maintenance end by CSCS team. Service providers check that services have come back online.(% style="color:#95a5a6" %) (% style="color:#1abc9c" %)Check this page for updates
132.1	53	* (% style="color:#1abc9c" %)15:20: Maintenance ended at 15:20 CEST time.
129.1	54
130.1	55	The storage back-end used by HBP/EBRAINS services has been causing some issues which have had repercussions on access to the object storage and OpenStack cloud service and thereby on HBP/EBRAINS services which run on this infrastructure. The issue has been identified and CSCS is ready to deploy a patch on the storage back-end. This will require that services running on OpenStack at CSCS be stopped for the duration of the maintenance.
129.1	56
130.1	57	There is never a good time for maintenance. We’re heading into a few weeks when more users will be on vacation, and some of the service providers may also be away. Hopefully this will impact as few people as possible. We apologize in advance for any inconvenience the downtime may cause.
129.1	58
128.1	59	=== Infrastructure issues at CSCS (2022-08-01) ===
127.1	60
129.1	61	The infrastructure at CSCS on which EBRAINS services run has failed over the weekend. August 1 was a bank holiday in Switzerland where CSCS is located. The situation was recovered before 10:00 CEST on Tuesday August 2.
127.1	62
129.1	63	The services affected were all those running on the OpenShift service at CSCS including:
127.1	64
128.1	65	* Collaboratory Lab at CSCS (please choose the JSC site when starting the Lab),
	66	* image service,
	67	* atlas viewers,
	68	* simulation services (NEST desktop, TVB, Brain Simulation Platform)
127.1	69
128.1	70	The planned maintenance listed below is expected to prevent the recurring issues that have been experienced over the past months.
127.1	71
128.1	72	We apologize for the inconvenience.
127.1	73
121.1	74	=== Infrastructure issues (2022-07-13) ===
	75
125.1	76	Several services on our EBRAINS OpenShift server running at CSCS were detected as having issues.
121.1	77
125.1	78	These issues may potentially affect services running on that OpenShift server including:
121.1	79
125.1	80	* Collaboratory Lab at CSCS (please choose the JSC site when starting the Lab),
	81	* image service,
	82	* atlas viewers,
	83	* simulation services (NEST desktop, TVB, Brain Simulation Platform)
121.1	84
126.1	85	The OpenShift situation has been resolved. Some services may need to be restarted. Please contact [[Support>>https://ebrains.eu/support]] if you identify a problem.
	86
125.1	87	The Collaboratory Bucket service (aka data proxy) has been intermittently down over the past several days due to an issue with the Swift archive/object storage at the infrastructure level at CSCS.
	88
126.1	89	We are working with the CSCS team to identify the cause of the issues with the Bucket service and we are having the infrastructure restarted any time issues occur. You can notify [[Support>>https://ebrains.eu/support]] if you identify any down time.
125.1	90
119.1	91	=== HBP and EBRAINS websites issue (2022-06-29) ===
	92
120.1	93	The HBP and EBRAINS main websites are down because of an issue with the .io top level domain DNS. This issue is preventing our websites from rendering images, CSS files, and other files referenced from the HTML of the web pages. The issue is not internal to our infrastructure nor to that of our cloud provider. We have decided to bring down the two websites for the time being.
119.1	94
120.1	95	The issue was resolved in the afternoon shortly after our provider confirmed their service had returned to nominal status.
	96
117.1	97	=== Issue with the Bucket service (2022-06-27) ===
	98
118.1	99	The bucket service (aka data proxy) is down due to an issue with the Swift archive/object storage at the infrastructure level at CSCS. The issue has been resolved. It was caused by the high availability load balancers located in front of the Swift storage at CSCS.
117.1	100
	101	We apologize for the inconvenience.
	102
114.1	103	=== Maintenance of the Drive (2022-04-14) ===
	104
115.1	105	The drive service will be down for maintenance on Thursday April 14 from 18:00 CEST for an estimated 2 to 3 hours. We are performing a routine garbage collection on the storage. During the downtime, users will not have access to the Drive: no reading/downloading of files, no adding/modifying files. This in turn means the Lab will not be usable either.
114.1	106
	107	We apologize in advance for the interruption and thank you for your understanding.
	108
116.1	109	The maintenance is done.
	110
112.1	111	=== Issue with the Drive (2022-02-05) ===
	112
113.1	113	The Drive server had an issue starting Saturday Feb 5 from 5 AM CET. The service was brought back online and was operational on Saturday. The issue was related to a disk full on the server caused by logs which then had other issues rebooting. No data was lost and backups were not affected.
112.1	114
110.1	115	=== Issue with OpenShift (2022-01-17) ===
	116
111.1	117	One of the NGINX servers running in front of our OpenShift service is down due to a problem at the infrastructure level. We are in communication with the infrastructure team to get the issue resolved as quickly as possible.
110.1	118
111.1	119	The issue was resolved by the infrastructure team. The server at fault is running again. All services are up and accessible again.
	120
108.1	121	=== Issue with the Collaboratory like/favourite feature (2022-01-13) ===
	122
109.1	123	The feature to like/favourite a collab was down for a day due to a change in the deployment of the Wiki service. This issue has been resolved without data loss. We apologise for any inconvenience caused by this issue.
108.1	124
107.1	125	=== Issue on the OpenShift server at CSCS (2021-12-28) ===
105.1	126
	127	The EBRAINS OpenShift server running at CSCS was detected as having come down. This issue affects all the services running on that OpenShift server including:
	128
	129	* Collaboratory Lab,
	130	* image service,
	131	* atlas viewers,
	132	* simulation services (NEST desktop, TVB, Brain Simulation Platform)
	133
	134	We are working with the CSCS team to reactivate the service ASAP.
	135
106.1	136	The service was reestablished at around 14:15 CET. The infrastructure team will continue looking into the potential causes of the problem with RedHat. The suspected cause lies in network access to the storage.
105.1	137
107.1	138	=== Issue on the Forum service (2021-12-27) ===
106.1	139
	140	The Forum service went down over the weekend along with one of the redundant OpenShift servers. The issue was due to a problem at the infrastructure level.
	141
	142	The Forum was unavailable for a few hours on Monday. There was not perceptible effect on the services running on OpenShift.
	143
107.1	144	=== Issue on the OpenShift server at CSCS (2021-11-24) ===
99.1	145
	146	The EBRAINS OpenShift server running at CSCS was detected as having come down at 16:00 CEST. This issue affects all the services running on that OpenShift server including:
	147
	148	* Collaboratory Lab,
	149	* image service,
	150	* atlas viewers,
	151	* simulation services (NEST desktop, TVB, Brain Simulation Platform)
	152
102.1	153	We are working with the CSCS team and RedHat (provider of the OpenStack solution on which OpenShift runs) to reactivate the service ASAP.
99.1	154
104.1	155	The issue affected the central VM node of the OpenShift service. Restarting the VM required that we resolve multiple issues including restarting at the same IP address and unlocking the storage volumes of that VM. (% style="color:#16a085" %)The central node has now been restarted. The same issue has occurred on three other instances of OpenShift VMs. They have been restarted too. OpenShift is up and running again. The DNS redirection(s) to the maintenance page is being removed. The services should be operational again.
102.1	156
104.1	157	(% style="color:#16a085" %)The root cause seems to be at the infrastructure level and RedHat is involved in analyzing that.
	158
100.1	159	We will keep updating this page with more information as it comes in.
	160
91.1	161	=== Maintenance of multiple services (2021-11-11 to 2021-11-19) ===
	162
98.1	163	We are migrating the last of our services away from an old cloud infrastructure. The production services were taken down on Wednesday November 17 and are now all back online. We will continue working on the non-production services, to return the services to the redundancy level prior to the migration, and various final tweaks.
93.1	164
98.1	165	Please contact [[support>>https://ebrains.eu/support]] about any new issues you identify on our services.
93.1	166
95.1	167	The services which were migrated during this maintenance include:

98.1	181	We apologize for the inconvenience and thank you for your understanding.
92.1	182
87.1	183	=== Technical difficulties on the Drive (2021-11-03) ===
	184
	185	The Drive has experienced some technical difficulties over the past weeks caused by multiple issues.
	186
	187	A reboot of the Drive server due to a hardware failure revealed an issue in the communication between the Lab and the Drive. A container is started for each Lab user who opens the Lab in their browser to run their notebooks. That container remains active by default well beyond the end of the execution of the notebook and the closing of the browser tab running the Lab, unless the users explicitly stop their container. Those containers were causing unusually high traffic to the Drive. We identified the problem and found a solution with an upgrade of the tool which the Drive is based on. We have had to shift the deployment date for this fix multiple times but we will be announcing the deployment date ASAP. In the meantime we ask Lab users to kindly stop their servers from the JupyterLab menu when they are not actively working in the Lab. This is done from the JupyterLab menu: //File > Hub control panel > Stop my server//.
	188
	189	The cloud infrastructure that the Drive is running on is being upgraded and the Drive service had to be moved to the newer servers. An incorrect management command of the server caused the migration of the data to be launched twice, with the second transfer overwriting production data dated Nov 2 with stale data from Oct 20. Several backup issues stacked on top of this problem. We have been able to recover a backup which was made on the night of Sunday Oct 31 to Monday Nov 1. We are verifying that we cannot identify issues with this data before we reopen access to the Drive. Some data loss is expected for data stored on the Drive after that backup and before we put up a banner asking users, as a precaution, not to add new data to the Drive on Tuesday Nov 2 around noon. Many countries had a bank holiday on Nov 1 so for many users, the data loss should be of a few hours on Nov 2.
	190
	191	We sincerely apologize for the problems incurred. We appreciate that the service we provide must be trustworthy for our users. We are taking the following actions to ensure that similar problems do not happen again:
	192
	193	* Review of the backup procedures on the Drive server which will be extended to all EBRAINS services which we manage.
	194	* Request notification from the underlying infrastructure when service accounts reach the limit imposed by their storage quota.
	195	* Improve the identification of production servers to reduce the risk of the operations team misidentifying which servers are running production service.
90.1	196	* Improve our procedure for communication about such incidents.
87.1	197
89.1	198	(% style="color:#16a085" %)The Drive service is up again. We have recovered all the data that we could. The Drive is working normally again. We will be performing a Drive upgrade ASAP. check the Wiki banner for more information.
87.1	199
	200	Additionally, the Collaboratory team will be looking into mirroring services onto more than one Fenix site to reduce down time when incidents occur. This task will be more challenging for some services than for others; it might not be materially feasible for some services, but we will be analysing possibilities for each Collaboratory service.
	201
86.1	202	=== Maintenance on 2021-10-19 ===
	203
	204	Due to migration to new hardware, various EBRAINS services will be down for up to 1 hour while these services and their data are migrated. Please See our [[Releases >>doc:Collabs.the-collaboratory.Releases.WebHome]]page for more information on our release.
	205
84.1	206	=== Infrastructure failure on 2021-10-04 ===
	207
85.1	208	A failure on the Openstack infrastructure at the Fenix site which hosts most of our services has brought down many EBRAINS service this morning before 9 AM CEST. A second event later in the morning at the same Fenix site brought down most other EBRAINS services. The infrastructure was brought back online in the afternoon and we have been reactivating services as quickly as possible. Some issues are still being addressed at the infrastructure level [17:00 CEST].
84.1	209
	210	We apologize for the inconvenience and thank all users for their understanding.
	211
83.1	212	=== SSL Certificates expiring September 30th ===
	213
	214	Our SSL certificates are produced by Let's Encrypt. One of their root certificates is expiring on September 30. This may cause issues for access to API services, especially from older browsers. You can find more information about these changes at the following links :
	215
	216	* [[https:~~/~~/letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/>>url:https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/]]
	217	* [[https:~~/~~/letsencrypt.org/certificates/>>url:https://letsencrypt.org/certificates/]]
	218
	219	As mentioned in the above links, if you are using one of our APIs, you should take the following steps to prevent issues:
	220
	221	* You must trust ISRG Root X1 (not just DST Root CA X3)
	222	* If you use OpenSSL, you must have version 1.1.0 or later

80.1	236	=== Openshift issues (2021-07-09) (Resolved) ===
72.1	237
76.1	238	The Openshift service has gone down. As the Collaboratory Lab and the Image service both rely on this service, they are currently unavailable. We are investigating this issue and it will be resolved as soon as possible. We apologise for any inconvenience caused.
72.1	239
80.1	240	UPDATE 2021-07-12: The issue seems to be with the Openstack servers. It is also affecting a few more VMs aside from the Openshift service. The infrastructure team is looking into it.
75.1	241
80.1	242	UPDATE 2021-07-12: The Openstack issue has been fixed. Services should be back up and running. Thank you for your patience.

	254
80.1	255	=== Drive issue (Resolved 2021-06-14) ===
70.1	256
	257	There is currently an issue that prevents the Drive option from appearing in new collabs. Although you can still create new collabs and can access all of the other functionality provided, you will not have access to the Drive by default. You can request a Drive be manually added to your collab via support.
	258	\\We apologise for any inconvenience this causes.
	259
	260
59.1	261	=== Drive issue (Solved) ===
18.1	262
59.1	263	Users have reported issues trying to access the drive. This is something we are aware of and trying to fix as soon as possible. This issue seems to be an Openshift problem.
20.1	264
59.1	265	Until this is resolved, users will have issues accessing any functionality that requires Drive access. This mainly concerns the Lab and to a less extant, any service that requires access to the drive.
22.1	266
59.1	267	Potential fix: We believe we have identified the issue and will be bringing the Lab service down for up to an hour at 10pm CEST on April 28th as we attempt to deploy this fix. All current Notebooks will be killed during this downtime. - Unfortunately this fix has not worked and we are looking at other solutions at the moment.
18.1	268
59.1	269	Potential fix 2: We have another small release that should fix the issue at 13:30 CEST Today. All currently running notebooks will be killed during this downtime.
18.1	270
59.1	271	This issue has been resolved, please let support know if you encounter any issues with the lab. Thank you for your understanding.
18.1	272
59.1	273	We apologise for any inconvenience this has caused
17.1	274
59.1	275	=== OnlyOffice license issue (Resolved) ===
	276
17.1	277	We are aware that some users are getting issues when trying to use OnlyOffice similar to the following image~:
	278
18.1	279	[[image:1613726704318-340.png]].
17.1	280
	281	We are working on this issue and will have it fixed as soon as possible, thank you for your patience and we apologise for any inconvenience caused.
	282
	283
59.1	284	=== SSL certificates (2020-12-04) (Resolved) ===
12.2	285
9.1	286	Our SSL Certificate provider (Let's Encrypt) has been using new certificates to sign our SSL certificates as described on their [[website>>https://letsencrypt.org/certificates]]. This requires updates on our servers and on your web browsers. The updates on your web browsers often go unnoticed by the user but in some cases your browser may inform you that it needs to fetch a new certificate. You can accept this safely; most browsers don't even mention it to the user.
7.1	287

59.1	293	=== Files locked in the Drive (2020-09-30) (Resolved) ===
1.1	294
4.1	295	A few users have reported issues in saving OnlyOffice edits to the Drive of a collab.
1.1	296
4.1	297	We are looking into this. At the time being, it seems that a small number of files are locked by the Drive which prevents OnlyOffice to update these files when they are edited online.
1.1	298
4.1	299	We are actively trying to correct the problem as promptly as possible.

4.1	301	==== The temporary workaround ====
2.1	302
4.1	303	When you open a file in OnlyOffice:
1.1	304
4.1	305	1. check if other users are editing the same file. The count appears at the top right corner.
	306	1. perform a trivial edit and save
	307	1. if you are the only user with that file open, you can trust the presence/absence of a warning message from OnlyOffice
	308	1. if multiple users have the file open simultaneously, you can:
	309	11. choose to trust the first user who opened it to have checked, or
	310	11. check in the Drive the timestamp of the file that you just saved
1.1	311
4.1	312	OnlyOffice will notify you when you try to save a file and the save fails. If that happens:
1.1	313
4.1	314	1. read the message
	315	1. use File > Download as ... > docx or pptx or xlsx to save the file to your computer
	316	1. close OnlyOffice. (% style="color:#e74c3c" %)DO NOT KEEP LOCKED FILES OPEN IN ONLYOFFICE.(%%) It would mislead others.
	317	1. rename the file by adding (% style="color:#3498db" %)//_UNLOCKED//(%%) at the end of the filename, before the extension
	318	1. upload the file with its new name
	319	1. work on this new file
1.1	320
4.1	321	We apologize for the inconvenience and thank you for your understanding.
