-===== 2019-06-25: Status Imagine Premium/Microsoft Azure Dev Tools =====
+===== 2023-12-12/13: TVS maintenance window =====
-Since Microsoft changed the name of the program from "Imagine Premium" to "Azure Dev Tools for Teaching", they changed the requirements for registration to the program portal, too. As for now, an institute email address is required for registration. As newer students are not longer provided with one of these, only older students with an old address are able to register. Microsoft is working on a solution to this problem, but as for now, there is no workaround. So we cannot provide you with access to the program at the time-being.

+This semester's data will be available until end of semester.
+<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>\\

-====== 2019-06-24: Loss of central Storage at B-IT ======
+===== 2023-08-07: Change  of WiFi Certificate of C.S.dept. and B-IT =====
-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.
+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 data rescue operation is completed by now, all services were restored again.
+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.\\

-===== 2019-05-20: eduroam, eduroam-cs and the new certificate =====
+===== 2023-02-02: Wifi services unavailable =====
-Until the replacement of the eduroam-cs certificate within IT, the certificate specified [[en:eduroam|here]] must still be used when connecting to eduroam-cs! We will have completed the conversion to the new CA within the next few days, so you can also use the new certificate within eduroam-cs, as stated in the HRZ newsletter. We will announce this accordingly here.

+**UPDATE (09:40h) : all wifi services are fully restored by now.**
-===== 2019-04-29: No Audio available in Room 0.107 =====
-Because of a device defect, there is currently no audio available in room 0.107. Please bring your own speakers or contact GSG for alternatives. We hope that the replacement amplifier will be installed during week 19.
+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.\\

-.220.4.11
+As the current certificate used for our wifi authentication services is about to
-.220.4.17
+expire, we will be updating to a new certificate soon. Your operating system could
-a00:5ba0:10:330::b
+be set up to notify you about this for security reasons. If this happens, you can
-a00:5ba0:10:330::11
+safely accept the new certificate and make sure it is the right one by comparing
+the certificate fingerprints to the ones issued on our [[en:wifistd|wifi documentation]] page.

+===== 2022-07-15: E-Mail service computer science & b-it unavailable =====
-(We will return our temporary network 131.220.50.0/23 to the University
-Computing Center shortly.)
-Most machines (computers, printers, scanners, etc.) are configured by DHCP
-automatically and have switched already, We have told about others, that we

+===== 2022-04-05: Authentication Problems with Matrix Service =====
-===== 2019-01-29: Scanning from the multifunction device "feder" in the BYOD room (U1.040) =====
+After the last Update of the matrix Service, some users may have experienced problems logging into out matrix service. This problem is now fixed. Existing sessions were not affected by this problem.\\
+\\
-It is now possible to scan from "feder" not only onto a USB storage device, but also into an E-mail. You have to

-login first, using the display of "feder" ("Alternate Login").
+===== 2022-03-03: new Chat-Function on GSG-Supportpages =====
-Please don't forget to log out afterwards.
+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.\\
