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

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

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.
