Tower Rd Data Center Firewall Outage

Starting roughly 9:55AM and lasting until around 10:15 one of the Tower Rd data center firewalls began dropping all traffic. The redundant firewall was still processing traffic correctly during this outage, however. The outage cause sporadic outages to services behind the firewall.
We are working to determine the full extent of the outage. The faulty firewall has been placed in a standby state and traffic is now flowing correctly though the redundant firewall.
