Problem with Blackboard Chat Tool: Wednesday, March 13, 2013

This week we started getting reports of the Blackboard Chat tool not working for some users. After investigation, it was determined that the latest language pack which was rolled out to production on Friday, March 8 caused issues with the Chat tool. The latest language pack will be rolled back to the original language pack tonight at 10 pm and after that we expect that the Chat should function properly.

We apologize for any inconvenience this may cause.

Slow network performance for East Side Admin and Academic subnets: Tuesday, Feb. 26 2013 1:00 PM

Slow network connectivity was reported by various users on the east side of the campus around 1 PM this afternoon.   The performance degradation affected Academic and Administrative subnets.  The cause of the problem was traced to a faulty fiber cable between two network switches, resulting in very slow download speeds.    The link was disabled and all traffic failed to a redundant link.   The faulty fiber will be replaced.

We apologize for any inconvenience this problem may have caused.
