Description

Service Restored at 2:20 p.m. on 3/26/2021: OIT email servers have caught up and have delivered all emails sent since the delay began. New emails will be delivered at the normal rate. Thank you for your patience as we worked to resolve this issue. 

Please Note: Some emails received today may have been sent over the last 24 hours. We recommend checking the time emails were sent as some email clients will sort messages using the time the message was delivered.

If you would like assistance with sorting your emails, or if you have any further issues receiving emails please contact the IT Service Center at oithelp@colorado.edu or call 303-735-4357.

 

Issue Updated at 1:00 p.m. on 3/26/2021: OIT email servers are beginning to catch up on the high load from the delays over the last 24 hours and email delivery is significantly increasing. We expect this will continue throughout the afternoon. We will post another update when the email delivery rates have returned to normal.

Please Note: While emails are now being delivered, they may have been sent over the last 24 hours. We recommend checking the time emails were sent as some email clients will sort messages using the time the message was delivered.
