[Faccus] UPDATE: Mailservices maintenance - August 25

What is happening? An issue arose during the mailservices upgrade this morning. As a result, some email was bounced and other messages were stalled.


*         Bounces would only have occurred for email that passed through mailservices on its way to connect. This includes mail originating off-campus, and from other hosts on-campus. It would not include email sent from a connect user to another connect user.



*         Mail to any host other than connect may have been stalled, but will be delivered very shortly.

Questions or concerns? Please contact the IST Service Desk, helpdesk at uwaterloo.ca<mailto:helpdesk at uwaterloo.ca> or ext. 44357.

Subject: Mailservices maintenance - August 25

What is happening? Maintenance will be performed on servers for mailservices.

When is this happening? Tuesday, August 25 between 7:00 and 8:00 a.m.

What is the impact? All mailbox servers will be rebooted (one at a time, requiring approximately 10 minutes each). Clients attempting to use the system during the maintenance window will receive a communications failure message while their server is down. Note: no message will be lost and no bounce messages will be sent/received.

Additional notes: During this maintenance window, greylisting will be disabled and the main load balancer will be replaced. No impact to clients is expected.

Questions or concerns? Please contact the IST Service Desk, helpdesk at uwaterloo.ca<mailto:helpdesk at uwaterloo.ca> or ext. 44357.
