- | ===== 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, | ||
- | |||
- | ** 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: | ||
- | |||
- | * BigBlueButton Load Balancer (bbb.informatik.uni-bonn.de) | ||
- | * a central file server of the B-IT | ||
- | |||
- | as well as the machines | ||
- | |||
- | * vm-wuebbel-01 | ||
- | * sentry | ||
- | * mail-info4 | ||
- | * bbb4mm | ||
- | * leonov | ||
- | * inf1-srv-01 | ||
- | * login.bit.uni-bonn.de | ||
- | |||
- | The affected systems are immediately shut down completely in order to accelerate the repair of the affected storage backend. After repairs have been completed, the systems will be moved to a newer cluster in the short to medium term. | ||
- | |||
- | The central BigBlueButton IT service is also affected, the individual BBB servers are available (ongoing conferences are not affected), but new rooms cannot be opened or existing ones can be entered. I hope to be able to use the load balancer again tomorrow at the latest. | ||
- | |||
- | I apologize for the inconvenience, | ||

- | ===== 2021-06-07 External Connectivity Issues ===== | ||

- | ===== 2021-05-31 Loss of All Network Connectivity. ===== | ||
- | |||
- | There has been a complete breakdown of all network connections | ||
- | within computer science at about ~17:00 due to an error in the | ||
- | Stack communication of our central router. Individual stack participants | ||
- | got into repetitive reboot loops. We could find the source of the problem | ||
- | and eliminate it. All services should be available again. | ||
- | |||
- | ---- | ||
- | ===== 2021-05-14 Downtime Staffhomes I/ | ||
- | |||
- | The staffhomes on these filesystems are available again, e.g. on login-staff: | ||

- | * /home/II | ||
- | * /labor/II | ||
- | * /home/IV | ||

- | |||
- | for staffers: login-staff.informatik.uni-bonn.de | ||
- | for students: login-stud.informatik.uni-bonn.de | ||
- | |||
- | The new fingerprints are available at the usual URL: | ||
- | https:// | ||
- | |||
- | The old servers will be available for you until friday (2021-03-05, | ||
- | 9:00am). At that time we will shut them down and redirect their DNS | ||
- | names to the new servers for some time to aid your migration there. | ||
