At 12:18pm Eastern today Level3 experienced an issue in a router within their network that caused disruption for connections passing through this upstream.

Traffic re-routed through other available providers and no other providers were impacted by this outage. The Level3 upstream connection is restored and stable at this time and the provider is investigating this issue with their own vendors.

These network issues can be difficult for us to detect as they don't impact everyone. For example, it didn't impact our outside monitoring systems, so we weren't notified of the issue.

We've added a trigger on our Network Interfaces to alert us of sustained drops in network traffic to help us more quickly identify this problem in the future.
