 +===== 2020-10-21: External Network Outage  =====
  
 +After a small Powerdisruption, all external network connections were down for about 20-30 Minutes. The local infrastructure of b-it and c.s.dept. was unaffected by this incident. 
 +
 +The Mailserver (which is located in the HRZ, which was affected more severly than us) will be available as soon as possible. Please be patient.
 +
 +**Update** The Mailserver is available again.
 +
 +----
 +===== 2020-10-17: Maintenance Window for the Network Infrastructure of the Serverrooms of C.S. Dept and B-IT =====
 +
 +At Saturday, the 17th of October 2020, beginning at 10:00 and lasting up to 17:00, the complete network infrastructure of the serverrooms of both the c.s. dept and the B-IT will be down for software upgrades. This will affect the whole IT-infrastructure of both institutes.

 +----
 +===== 2020-09-28: The Aftermath of a Power Outage =====
 +
 +Due to a power outage in the early morning, there were massive connectivity problems throughout the university networks. 
 +
 +In the computer science dept., all systems without direct UPS-support were affected, but these problems should all be fixed by now.
 +
 +----
 +===== 2020-09-22: Changes for wireless networks CP1GUEST and EDUROAM-CS =====
 +Due to routing changes of the abovementioned networks, we anticipate a few discontinuities for them. If you have a CS/B-IT account, we remind you that you should better use [[en:wifistd|our internal network ''802.1X'']] (which most likely won't be affected this time).
 +//Update:// The activities have been terminated for the time being.
 +----
 +===== 2020-09-17: Maintainance of Internet Connection: finished  =====
 +Due to maintainance of the Internet connection, individual services might be disconnected for a short time today. Normally, you can reconnect right away.
 +----
 +===== 2020-09-01: New Service: Matrix IM  =====
 +We just finished the deployment of a node of the matrix.org instant communication network. More info can be found [[en:xmpp|here]].
 +
 +----
 +===== 2020-08-17: Maintainance of Account server  =====
 +The maintainance of the account creation and renewal website, startup, is finished.
 +----
 +===== 2020-08-10: DNS Resolving last Weekend  =====
 +
 +From sunday, ~13:00 up to today, ~9:30, we experienced minor problems throughout the entire network of the c.s. dept and the B-IT due to a failing primary nameserver. The problem was corrected by now.
 +
 +----
 +===== 2020-05-03: Mailservice temporarily down =====
 +
 +Due to failed network equipment in the HRZ the mail server is offline at the moment. Please be patient while the problem is solved.
 +
 +UPDATE: the problem has been solved, the mail service is available again.
 +
 +----
 +===== 2020-04-24: Discontinuation of OSP Videostreaming =====
 +
 +Due to massive problems with the software Backend, we had to shut down our streaming services on the OSP server permantly.
 +
 +
 +----
 +===== 2020-03-18: Reduction in attendance times due to COVID-19 =====
 +
 +Due to the special situation we find ourselves in these days, we decided to reduce our attendance service to the absolute minimum possible for the foreseeable time. Further information is available [[en:covid-19|here]].
 +
 +----
 +===== 2020-03-05: Availability of the Computer Pool Rooms U1.012, U1.041, U1.042 =====
 +
 +After the end of the [[https://www.informatik.uni-bonn.de/de/Pressemitteilungen/schueler-krypto-botschaften-verschluesseln-im-auftrag-ihrer-majestaet?set_language=en|Schüler-Krypto 2020]], the above mentioned pool rooms and the computers in there have been returned to their regular use.
 +
 +----
 +===== 2019-06-25: Update Status Imagine Premium/Microsoft Azure Dev Tools =====
 +
 +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 =====
 +
 +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.
 +
 +----
 +====== 2019-06-24: Loss of central Storage at 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.
 +
 +The data rescue operation is completed by now, all services were restored again.
 +
 +----
 +===== 2019-05-29: New Host Keys login.bit =====
 +
 +The SSH Login Server of the b-it was reinstalled and received new host keys. If you want to verify, please refer to the following fingerprints:
