On Saturday, October 18, this WordPress service suffered it longest outage, which lasted approximately 12 hours. On Sunday there was another outage for an hour right before noon.
The reason for this outage was a misconfigured Kace appliance server that was monopolizing all of the http processes on our servers. The Kace server was taken offline Saturday evening, and normal service returned. Then someone brought the same server back up on Sunday morning (without regard for our service), and the outage resumed.
The errant server was moved behind a different firewall, so this exact outage should not happen again. However, we will take steps in the coming weeks to guard against changes to the environment taking down our service again.
I apologize for this outage and the general unreliability of our WordPress service.
