Update #1 - CS DNS servers were restarted on Monday. Issue was resolved after that...

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,

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.

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,

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.

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.

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.

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

Civ V
Artemis
Team Fortress 2
League of Legends
Super Smash Bros.
Mortal Kombat
The Ship
Risk

Tournaments: Due to the last minute nature of this event, there will be no "official" gaming tournaments, however, those who come are free to organize tournaments or mass-gaming events as they please (including and especially Artemis and Civ V).
