It seems UCIS had some kind of power fail event thismorning, resulting in many core services (including the network) going offline. The disruption was most apparent from (approximately) 10:30 to 11:30am, but some small glitches still appear to be ongoing.

As of 2pm things appear operational but with "some minor inconsistent network performance issues".
