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.
