Wireless interruption on Wednesday, Sept 27, 2017 at 10:40 AM

Posted on September 27, 2017 by Brian Lesser

At 10:40 AM a Wireless Distribution Switch (WDS) stopped forwarding Wireless Access Points (WAPs) keep-alive heartbeats to their home wireless controllers. As a result all affected WAPs failed over to their backup wireless controllers to re-establish connectivity. WDS returned to service at 10:48 at which time the affected wireless access points started the process of migrating back to their home controllers. The resultant re-convergence of the wireless access points resulted in intermittent wireless service as network connectivity was re-established. Full service returned as of 11:10 AM. Network Engineering will be conducting a further investigation into this network switch issue.

Please accept our apologies for the problems this morning’s service interruption caused.

Starting at  4:06 AM, on Thursday, August 29, 2017, a main database went to Read-Only mode. This is impacting access to many of Ryerson’s applications such as jobs on campus, research grant and housing. CCS technical administrators are currently investigating the problem.

Update:

The issue was traced  to a defective storage controller where many databases are stored such as HR and www. Databases were recovered and all services resumed at 9:45

Update 2:

During a scheduled replacement of the defective storage controller on Wednesday afternoon a few applications experienced an unplanned outage, including RMail, research grant and housing.   The impact lasted from approximately  6:30 PM to 8 PM.
