This incident has been resolved.
Feb 15, 11:52 EST
As of 9:45pm, network and IT service performance has returned to normal.
The root cause of this event was a distributed denial of service (DDoS) event targeting the student network. Although we have campus-level and internet provider-level protections in place against DDoS attacks, this was a very large event that had an effect on the operation of our network. The size of this event, however, created difficulties for the campus network even with those protections in place.
T&I will continue to monitor this situation.

T&I staff are continuing to investigate this issue. Faculty/staff attempting to access campus IT services from off-campus through VPN may notice difficulties connecting to VPN or logging into data center applications once connected. Campus-hosted services accessed without VPN may also be experiencing sporadic difficulties.
Cloud-hosted services, including email, Dropbox, G Suite (Google Apps), and single-sign on authentication/Duo MFA, should not be affected by this outage, and appear to be operating as expected at this time.
We will post further details as we have them. If you have further questions or to report additional impact to IT services or the campus network, please contact the T&I Support Center at firstname.lastname@example.org
or (704) 894-2900.
