+===== 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.
+The VPN service is *not* affected by these changes.\\

+=====2023-07-14: Configuration change also for "eduroam-cs"=====
-===== Guest WiFi available for Workshops and conferences etc. =====
+The [[https://www.hrz.uni-bonn.de/en/news/reinstall-eduroam-on-all-end-devices-by-15-july-2023|configuration change/re-installation of Eduroam for members of Bonn University]] is also necessary for the Eduroam branch in our building (eduroam-cs). The updated configuration parameters are [[en:eduroam|available on our Web page]].
-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.
+According to HRZ, a connection with the old parameters **won't be possible after July 15th, 2023**.
+If you have an Informatics/B-IT account issued by us, you can (and should preferably) use the network _802.1X_ in our building. [[en:wifistd|Here are the usage instructions.]]\\

+===== 2023-02-02: Wifi services unavailable =====
+**UPDATE (09:40h) : all wifi services are fully restored by now.**
+We are currently experiencing a total loss of WiFi authentication
+inside the whole building of the Computer Science Dept. and the B-IT due
+to a failure of a central component.
+We are already working on a solution to the problem. Unfortunately we
+cannot predict how long these repairs will take. Due to the nature of
+the problem, it could be a longer process.
+Other services are not affected by the disruption.\\

+**UPDATE 2022-07-25:** the certificate was successfully replaced.

+expire, we will be updating to a new certificate soon. Your operating system could
+be set up to notify you about this for security reasons. If this happens, you can

+the certificate fingerprints to the ones issued on our [[en:wifistd|wifi documentation]] page.

+===== 2022-03-03: new Chat-Function on GSG-Supportpages =====
+As we are trying to further accomodate incoming support requests especially from students, we added a new chat function to this page to give you an opportunity to request aid directly from us without the need for a physical helpdesk. If this service is maintainable, we will try to implement it into other central services (like i.e. WUMI).
+If you want to use the chat, just click on the blue bar on the bottom right part of the page footer.\\
