-===== 2021-07-27: unscheduled downtime of BigBlueButton, a b-it fileserver and some VMs =====
+===== 2021-10-23: BigBlueButton Maintenance =====
-**Update 13:00, 2021-07-30:** The file server services were restored. Some files are still pending in the restore, we are trying to reintegrate the latest data from the backup during the weekend in order to fully reach the state of 07/27, 01:56. We hope to be able to reconstruct more recent data from the original storage at the beginning of the week, but this should be requested from us on a case-by-case basis, should any relevant data really be missing by Monday.
+**Update:** the Upgrade was successfully completed.
-**Update 15:40, 2021-07-29:** As we can already see by now, the restore will take until tomorrow, there are just too many small files inside the unix homes.
+Starting at around 11:00 am, we will undergo a comprehensive upgrade of the entire BBB environment to the latest software versions. Since a long overdue restructuring of the load balancing and DB backend systems is pending at the same time, there is unfortunately a longer downtime. Basic functionalities may also be available again at short notice, but the cluster will not be able to develop its full scope of services until late in the afternoon. We expect the work to be completed around 5:00 p.m.\\

+===== 2021-10-01: BigBlueButton slides and whiteboard functionality available again =====
-**Update 9:51, 2021-07-29:** At this moment we already restored 4.5 of 7.5 TB of data (last backup ran at 2021-07-27 01:56:21) to the B-IT fileserver. We are hoping to finish the restore until the end of this day, so that we should be able to restore the availability of this service tomorrow morning at the latest.\\
+a workaround for the problem has just been implemented; Currently running
+BBB meetings will not benefit from this yet, but the following ones
+will once again have slides and whiteboard functionality.
+Please note that the workaround may fail on some systems due to
+cached redirects; if this happens on your browser, please clear all of your browser caches that are associated with the BBB nodes
+bbb-node*.informatik.uni-bonn.de or use a alternative browser until the redirects
+in your standard browser have expired.
+Thus, the full functionality of the BBB should be restored for the time being.\\
 \\
-**Update 11:09, 2021-07-28:** most VMs are back online again. The UNIX Home Servers at b-it have to be restored from tape, which will still take a considerate amount of time.\\
+----
+===== 2021-10-01: BigBlueButton service without slide functionality =====
+Probably as a result of yesterday's problem, no more slides can currently be displayed in the BBB. Thank you to everyone who reported the problem to us, we are already busy solving the problem. \\

+Overleaf is once again up and running. All Accounts need to be re-created due to the Database-Errors.\\
+\\

+===== 2021-08-06: unscheduled downtime of overleaf =====
+Due to inconsistencies in the DB backend, the overleaf instance of the C.S.Dept. is down at the moment.\\

+===== 2021-07-27: unscheduled downtime of BigBlueButton, a b-it fileserver and some VMs =====
+** Update: All central services are by now fully available again. **
 Due to problems with the storage backend of an older virtualization cluster, there are currently massive problems when using some VMs, in particular:
