Possible Disruption of Service -- Wednesday, January 21st starting at 6:00 AM
The Central Authentication System (CAS) which is used to log into Waterloo LEARN will be updated starting at approximately 6:00 AM tomorrow morning (Wednesday, January 21st) and may result in a possible disruption of service until 8:00 AM. Users attempting to log into Waterloo LEARN during that time frame may encounter difficulty accessing the system and are encouraged to try logging in again after waiting a short interval.
The issues of e-mails being delayed by up to 48 hours is believed to be resolved. IST staff have determined the issue appears to have been caused when the university experienced an e-mail distributed denial of service attack. Testing has concluded that e-mail is again sending properly using LEARN. If you have any questions, please contact learnhelp@uwaterloo.ca.
