NOTICE: Server downtime planned between 12PM and 3PM Saturday March 19th

Hello,

Prior to the LAN party on Saturday the SIG Sysadmin group plans on doing some maintenance on the ACM servers. During this period the website, secure shell access, ACM email, and file access may not be available. We do not expect these services to be down to the entire duration of the downtime period and will be sending out additional mail notices before any services are actually taken offline the day of.

For those who will be in the office a little early on the 19th, access to the internet via the ACM LAN network is NOT one of the services that will be offline during this time. :D

Please direct any questions to the SIG mailing list: sigsysadmin@acm.cs.uic.edu

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,

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

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.
