- | ====== 2019-06-24: Loss of central Storage at B-IT ====== | + | ===== 2023-02-02: Wifi services unavailable |
- | Last Friday around noon we experienced a total loss of several central components of our userstorage for UNIX (NFS) and Windows (SMB). Sadly we had to realize that we lost a rather important large storage component completely, so we had to recover the affected storage areas from our backup to alternative server systems. Because of that, a certain loss of data in the confines of the regular backup schedule (usually daily in the night) has to be expected. | + | **UPDATE |
- | The data rescue operation is completed by now, all services were restored again. | + | 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. | ||
