February 2026: Network Issues

Detected Feb 26, 2026 10:44 AM EST · Resolved Feb 27, 2026 3:36 AM EST · Duration about 17 hours

NTA experienced a major network outage lasting 16.9 hours that affected all core services including calls, mobile applications, web interfaces, and integrations due to a flapping primary network connection that prevented automatic failover systems from activating. Engineers manually disconnected the problematic link at the datacenter to restore service using backup connections, with restricted service resuming after approximately 1 hour and 10 minutes, followed by full restoration about 43 minutes later. The incident required on-site intervention because the failover mechanisms only engage when connections are completely down, not when they are intermittently flapping.
