Degraded Service - 2/26/2016 - [Resolved]

SysAdmins are currently looking into an issue causing ACM services not to authenticate correctly.  We are currently looking into the issue and will announce more information via the website once we know more.

 

Current known issues:

  • Workstations cannot authenticate
  • acm.cs.uic.edu cannot authenticate AD users

If you see something broken, please report it to the systems mailing list:

sigsysadmin@acm.cs.uic.edu

 

Thanks you for your patience,

Chase Lee

 

Update #1 - This issue was caused by a malfunction in the cooling unit.  Engineers have been dispatched to remedy the issue.  Some servers automatically shutoff due to ambient heat.

Update #2 - Cooling unit is back up. Servers have been restarted.  Sysadmins will continue to monitor the situation for the rest of the day.

Server Maintenance Concluded

Update: All outstanding problems have been solved

Unfortunately this round of maintenance had some issues spark up on us and our window of instability was longer than we would have liked, but all services should be functioning normally at this point.

There are a couple exceptions:

  • ACM Mumble is currently down due to issues with it connecting to backend authentication
  • brink.cs.uic.edu is currently inaccessible as the host virtual machine did not start up correctly
  • acm.eecs.uic.edu is currently inaccessible as the VM hosting the beta for an updated website also failed to startup correctly

That said, there are things we may have missed while we put out the big fires. So, if you see something broken, please report it to the systems mailing list

sigsysadmin@acm.cs.uic.edu

 

Thanks for the Patience,

Walter

Server Maintenance Notice, Downtime between 5:30PM and 6:30PM today

The Sysadmin group will be finalizing some software updates during our meeting today between 5:30PM and 6:30PM. During this time various services hosted by the UIC ACM will go down as we begin our work. We will send follow up mail if difficulties are encountered that might extend downtime and when services have been restored.

Gitlab Public Access FIXED!

The public access to the ACM Gitlab instance located at acm.cs.uic.edu/git has been fixed and should now be accessable through normal means. Please report any further issues to webmasters AT acm.cs.uic.edu.

Gitlab Public Access Offline

Due to an unknown problem with our web hosting setup, the Gitlab web interface and repos are currently not accessable via acm.cs.uic.edu/git. We are working on steps to resolve the issue, but in the mean time you will be unable to push or pull from our git server. The Git reposiatories themselves are unaffected by this issue so any data on our system will be there when access is restored. Sorry for any inconveince this has caused.

Intermittent Internet Connectivity - Fall 2015

It has come to the attention to the ACM/LUG System Administrators that the internet connection seems to drop randomly. In general, the service interruption lasts for only a few minutes. We are currently looking into the issue, but as of yet, we do not have any evidence as to why this actually happens. This issue is difficult to debug due to the fact that it does not appear to happen at any set intervals. The System Administrators will continue to look into the issue, however we do not currently have an estimate as to when this issue will be resolved. We will attempt some infrastructure changes over the next few months in order to mitigate the occurrence of these outages. We apologize for any inconvienences these outages may have caused.

Affected Servers:

  • ACM/LUG Workstations
  • Most servers on internal IP ranges

Affected Services:

  • Internet Connectivity
  • Wifi Internet Connectivity
  • VOIP Phone
  • Websites

If you have any questions about this, please contact your friendly neighborhood Sysadmins at: sigsysadmin [at] acm.cs.uic.edu

 

Thanks,
