 +===== 2023-12-11: Eduroam was out or order =====
  
-===== 2018-09-05Status of the core network routing problems =====+<del>As the Universities Computing Center  [[https://unibonn.statuspage.io/|conveyed (see there for news)]], the [[en:Eduroam]] access is out of order.</del>
  
-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. +<html><div class="tpl_update">Eduroam is working again.</div></html>
- +
-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. +
- +
-We thank you all four your continuous patience and support.+
  
 +Members and students of the Computer Science department and the  B-IT can also use our own [[en:wifistd|wireless network "802.1X"]].\\

 +===== 2023-12-12/13: TVS maintenance window =====
  
-===== 2018-09-03: Further problems with our central network routing components =====+<html><div class="tpl_update">The tutorial assignment system is operational again.</div> 
 +</html>
  
-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. +This semester's data will be available until end of semester.
- +
-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.+
  
 +<del>TVS will not be available on 12th and possibly 13rd of December //from 10am to 12pm,// while doing a software update.
 +If you still need your data, please read them out before. This will also be possible afterwards, of course, </del>\\

 +===== 2023-08-07: Change  of WiFi Certificate of C.S.dept. and B-IT =====
  
-===== 2018-08-31: Maintenance window of central network routing components =====+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).
  
-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.+This means that all wifi configurations of your devices that are used to 
 +connect to the computer science dept. or the b-it (eduroam-cs and 
 +802.1X) have to be reconfigured to check for the new certificate/and 
 +or CA.
  
----- +You will find the current [[en:wifistd|fingerprints and certificate downloads]] at the usual place.
-===== 2018-08-28Outage 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.+
  
 +The VPN service is *not* affected by these changes.\\
