Ok, first blog post here...
On sunday, our machine room's UPS caused a brief power failure, which unfortunately tripped some breakers so we had to call out the electricians before we could start restoring service.
The UPS will take some time to repair, so Durham will be at risk for a while.
On the plus side, the changes involved with the SE rebuild have been proven to survive a reboot!
Just realised that I forgot to say that the site is back online, and has been since sunday evening, it is just currently at mercy of the power company.
