On Tuesday, October 6, 2015 at 4:15 PM, the authentication system for wireless users failed. This prevented new wireless session from being established. Network services team is investigating the problem.
Update:
The problem was traced to an overload of authentication requests that exceeded a conservative threshold. The threshold has been increased to alleviate the problem and services resumed at 6:45 PM
Please accept our apologies for any inconvenience this has caused.
