-===== 2018-09-14: Maintenance WiFi Networks =====
+===== 2021-03-01: New SSH Login Servers  =====
-Due to the continued problems with our core router, we are trying to take some load away from it by changing the routing configuration of our WiFi Networks to other components. BEcause of that you can expect some outages of the wifi throughout the day.
+We deployed two new ssh login servers for you:

-===== 2018-09-05: Status of the core network routing problem =====
+for students: login-stud.informatik.uni-bonn.de
-We just experienced another network outage, which was intended this time to collect data for the problem analysis of the hardware vendor. We continue to work on a solution, utilizing our support contractor and the hardware vendor.
+The new fingerprints are available at the usual URL:
+https://gsg.cs.uni-bonn.de/doku.php?id=en:ssh:fingerprints
-By now we punched down the possible suspects to the IPv6 core of the router, which now remains disabled to ensure a stable IPv4 operation.
+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
-We thank you all four your continuous patience and support.

-===== 2018-09-03: Further problems with our central network routing components =====
-As the recent proceedings in patching up our central routers were not successful, we are continuing to experience massive problems with our core network, resulting in massive performance issues and complete blackouts of network connectivity. This problem is of a non-trivial nature, we are continuing to investigate the issue, utilizing our support partners and the hardware vendor itself.
-At the moment we seem to have pinned down the problem to the IPv6 core of the router. To stabilize the situation as good as possible, we have disabled IPv6 routing for the time being, hoping to reactivate it after resolving the problem.
-Please continue to be patient and remember that the whole setup in this building is completely new, some problems simply were to be expected.

-===== 2018-08-31: Maintenance window of central network routing components =====
-In the time between 7:30 a.m. and 9:00 a.m. we will update the central routing components. As a direct result there will be total network service outages during this period in the whole c.s. dept. and the b-it. We apologize for the inconvenience.
-----
-===== 2018-08-28: Outage of network connectivity =====
-We just experienced a breakdown of the central routing components of the c.s. dept and b-it. the problem was corrected and we are investigating the cause.
-Thank you for your patience.
