- | ** Update: All central services are by now fully available again. ** | + | Today we did renew the certificate for our wifi infrastructure. At the same time we switched over to the new certification authority hosted |
- | Due to problems with the storage backend | + | This means that all wifi configurations |
+ | 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/ | ||
+ | or CA. | ||
