We have both our HVAC and Controls Systems vendors on site right now performing an investigation of our issue over the weekend. They will be shutting off the systems for short periods of time in order to perform diagnosis of various system components. Datacenter temperatures may rise as a result. Recover times should be brief however, as the outside temperature here in Seattle is 30F/17C cooler than it was on Sunday with cloudy skies, showers and 53F.
