-===== 2021-07-27: unscheduled downtime of BigBlueButton, a b-it fileserver and some VMs =====
+===== 2025-04-24: Feder scanner faulty =====
+<html><div class="tpl_update">The scanner is working again.</div></html>\\
-**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.
+<del>Scanning and copying is not possible at the moment. A technician will come shortly to fix the issue. Printing is still possible.</del>
-**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.\\
 \\
-**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.\\

+===== 2024-10-23: Unclean printing on Feder =====
+<html><div class="tpl_update">Feder prints cleanly again</div></html>\\
+<del>The printer "Feder" isn't printing cleanly at the moment, we are currently awaiting delivery of a required replacement part.</del>
 \\
-**Update 22:26, 2021-07-27:** the BigBlueButton Service is fully functional again.\\

+===== 2024-08-06: Feder out of order =====
+<html><div class="tpl_update">Feder is working again.</div></html>\\
+<del> Printing with Feder is not possible at the moment. We're working on a solution. </del>\\
 \\
+----
-Due to problems with the storage backend of an older virtualization cluster, there are currently massive problems when using some VMs, in particular:
+===== 2024-07-31: Feder A4 printing only =====
+<del> Printing is only possible through Tray 5 (on the side). Thus A3 prints are not available at the moment.</del> //
-  *  BigBlueButton Load Balancer (bbb.informatik.uni-bonn.de)

+===== 2024-06-12: Eduroam-CS available again =====
-as well as the machines
+<del>Currently, WLAN authentication in "Eduroam-CS" is distrupted due to a hardware problem in the proxy machine user. We're working on a fix.</del>\\

-  * 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, we are working on eliminating the problem.

-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.
+If you are a user of Apple devices, you can utilize our new [[en:wifistd#macosios|Configuration profiles]]. If you experiencesd connectivity problems in the last weeks, these new profiles should solve your problems.\\

-===== 2021-03-01: New SSH Login Servers  =====
+===== 2023-08-07: Change  of WiFi Certificate of C.S.dept. and B-IT =====
-We deployed two new ssh login servers for you:
+Today we did renew the certificate for our wifi infrastructure. At the same time we switched over to the new certification authority hosted by the DFN (GEANT, just like the HRZ did some days before, you may remember the mail about eduroam).
-for staffers: login-staff.informatik.uni-bonn.de
+This means that all wifi configurations of your devices that are used to
-for students: login-stud.informatik.uni-bonn.de
+connect to the computer science dept. or the b-it (eduroam-cs and
+.1X) have to be reconfigured to check for the new certificate/and
+or CA.
-The new fingerprints are available at the usual URL:
+You will find the current [[en:wifistd|fingerprints and certificate downloads]] at the usual place.
-https://gsg.cs.uni-bonn.de/doku.php?id=en:ssh:fingerprints
-The old servers will be available for you until friday (2021-03-05,
-: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.
+The VPN service is *not* affected by these changes.\\
