Web Operations & Support noticed sites were not loading and uptime monitors alerted.

Several Mason websites were not functional during the outage.

Firewall vendor experienced upline network outages.

Opened ticket with vendor to report issue, waited for vendor resolve. In the meantime, we routed DNS for prime sites, such as www.gmu.edu, its.gmu.edu and police.gmu.edu out from around the firewall so websites would be functional during firewall outage.

Vendor was not able to share a lot of details about the outage for security reasons but they noted they are taking steps to prevent future downtime.
