-===== 2018-09-14: Maintenance WiFi Networks =====
+===== 2025-08-27: Printer Feder is available =====
+<html><div class="tpl_info">Feder (student printer in U1.040) is printing again.</div></html>\\
-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.
+The replacement part has reached us and was installed.
 ----
-===== 2018-09-05: Status of the core network routing problem =====
+===== 2024-06-12: Eduroam-CS available again =====
+<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>\\
-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-cs 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.
 ----
+===== 2024-05-22: Plotter service was unavailable =====
-===== 2018-09-03: Further problems with our central network routing components =====
+<del>Due to some hardware issues plotting services are unavailable at the moment. We apologize for any inconveniences.</del>\\
+<html><div class="tpl_update">Plotting services are available 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.
-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.
 ----
+===== 2024-05-08: New WiFi Configuration Profiles for Apple devices =====
-===== 2018-08-31: Maintenance window of central network routing components =====
+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.\\
+\\
-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 =====
+===== 2023-12-11: Eduroam was out or order =====
-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.
+<del>As the Universities Computing Center  [[https://unibonn.statuspage.io/|conveyed (see there for news)]], the [[en:Eduroam]] access is out of order.</del>
-Thank you for your patience.
+<html><div class="tpl_update">Eduroam is working again.</div></html>
+Members and students of the Computer Science department and the  B-IT can also use our own [[en:wifistd|wireless network "802.1X"]].\\

 ----
+===== 2023-08-07: Change  of WiFi Certificate of C.S.dept. and B-IT =====
-===== Commissioning the new print account =====
+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).
-The printing system known from the Römerstraße is online in a revised version since Monday, 06.08.2018. Further information can be found in the tab "[[en:print | Print Services]]".
+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
+.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.
-===== Guest WiFi available for Workshops and conferences etc. =====
-For any sort of special event or just for short-time guests we are now offering temporary access to our WiFi infrastructure through a sponsored [[en:guestaccounts|guest portal system]]. If you are hosting an such event or awaiting guests, please [[mailto:gsg@informatik.uni-bonn.de|contact us]] for further information.
+The VPN service is *not* affected by these changes.\\
