As we noted in an earlier post, we experienced an unscheduled outage with our On Demand services (FogBugz, Kiln, and StackExchange) that lasted about 10 minutes.
This was initiated by a hard fault on our primary load balancer. Its redundant peer took over as planned, but was somewhat confused about the transition. It took a few moments to put things back in order, and then all services returned to normal.
Since then, we have identified both the primary cause of the fault on the original system and the misconfiguration that caused the noted 'confusion' on the backup.
We offer our sincere apologies for this disruption, and appreciate your patience in the matter.
