Our system was sporadically offline this afternoon due to a power outage at the Tucson datacenter where we colocate our servers. Normally their UPS (uninterruptible power supply) provisions with on-site power generators would handle such events seamlessly, but in this case they'd discovered their UPS had failed into bypass mode a few days ago, and fixing it apparently required cutting power entirely. We're a bit perturbed (to put it mildly) that they decided to schedule this maintenance for mid-afternoon on a weekday without giving any advance notice, but suffice to say this is yet another reason why we're already investigating strategies to migrate E-junkie to more reliable hosting provisions.
