Patmos - Phoenix Datacenter Network Accessibility – Incident details

Root Cause Analysis
On 9/25/25 at 4:50 MST, clients relying on internal DNS in our Phoenix data center experienced connectivity loss for approximately 90 minutes. The outage was caused by a switch reload that did not retain firewall connectivity settings. Once the settings were restored, full connectivity was re-established. The firewall configuration has now been saved to prevent recurrence during future switch reloads.

The network is now fully operational, and we continue to closely monitor its performance. A detailed root cause analysis will be shared once it is complete. Please refer to this page for any further updates.
