 +===== 2019-12-17: Attendance Times during the Holidays =====
-===== 2018-09-05: Status of the core network routing problems =====+During the holidays (starting with the 2019-12-23  up until 2020-01-03) we will not be available to you personally at our offices.
-We just experienced another network outage, which was intended ​this time to collect data for the problem analysis of the hardware vendorWe continue to work on a solution, utilizing our support contractor and the hardware vendor.+If there is some kind of technical emergency during ​this time, please send an email to
-By now we punched down the possible supects to the IPv6 core of the router, which now remains disabled to ensure a stable IPv4 operation.+---- 
 +===== 2019-06-25: Update Status Imagine Premium/​Microsoft Azure Dev Tools =====
-We thank you all four your continuous patience and support.+By now a registration using the university email address is possible. More information available on [[en:​microsoftimagine|this page]].

 +===== 2019-06-25: Status Imagine Premium/​Microsoft Azure Dev Tools =====
-===== 2018-09-03: Further problems ​with our central network routing components =====+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.
-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.+---- 
 +====== 2019-06-24: Loss of central Storage at B-IT ======
-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.+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.
-Please continue to be patient and remember that the whole setup in this building ​is completely newsome problems simply ​were to be expected.+The data rescue operation ​is completed by nowall services ​were restored again.

-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.+SHA256:

-===== 2018-08-28Outage of network connectivity ​=====+===== 2019-05-20eduroam, eduroam-cs and the new certificate ​===== 
 +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.
