Yesterday afternoon (Pacific time), our data center provider (<datacenter name>) was performing some upgrades to their UPS devices. We are still gathering details, but power to the data centre was lost and our equipment there was interrupted. While our servers have dual power supplies, the power outage affected both circuits.
