Update - IST Network Services will perform a firmware update for the wireless controllers on Monday, April 28th, from 5:00 AM to 8:00 AM.
During this maintenance window, there will be a temporary outage affecting the wireless network. Only a limited number of access points will reboot at any given time, so Wi-Fi coverage will remain available in most areas across campus.
We expect the update to be completed within the scheduled window, and normal service will resume after.

Investigating - IST is aware that some users are receiving the error 'Failed to create session manager entry' when attempting to connect to the campus VPN. The error is presented due to resource exhaustion on the VPN devices, caused by excessive authentication attempts from malicious sources.
Mitigations have been put in place to block the bad actors, so that resources are free for normal use.
Clients who are still experiencing the problem after 11:00 AM are encouraged to submit a ticket to IST.
