Tonight, March 13, at 9:39pm, a core router in the northern California telecom network stopped responding. We are working to restore service and determine why traffic is not routing around.
Update(11:36pm): We have isolated and routed around the responsible equipment. The equipment in question was silently black-holing a large portion of traffic flowing through it. Customers network wide may have experienced degraded or interrupted service. All affected services appear to be restored at this point and we will be working with our hardware vendor to ensure this does not happen again.
