Update Oct 06 4:50pm: ITS has completed the migration to the new firewalls and has resolved the issues experienced after the upgrade. 

Problems were experienced with a widespread portion of the network not being able to reach the Internet and VPNs were not working.  The problems were caused by a previously undetected problem with the new firewalls and we worked with our support partner to identify and work around the problem.

This upgrade is required to increase the capacity, stability and speed of the campus cybersecurity infrastructure.


Emails being returned undeliverable

IT Services has become aware that there was a problem delivering some email messages sent from Office 365 to students or to ourside the University.  The message would appear to be sent normally, then after two days would be returned to the sender as undeliverable.

This problem was caused by a change in the Office 365 email system that resulted in the messages being blocked by our anti-spam controls.  We have adjusted our system and all remaining and new messages will be delivered normally.
