From what I hear the Miles platting incident was earlier in the day and may not be connected The incident that turned the lights off in the city was caused by an unspecified failure the other side of town a couple of hours later.
One area that did feel the full effects of the outage was Salford Quays which is home to a number of data centres. It is power failures at these data centres which will have caused the internet to go off line.
When the power went back on most equipment came back on however it all turned on at the same time and so came online out of sequence and in some cases some things didnt turn on at all. domain servers would have come on line before DCs and things came on in safe mode etc.
I personally spent all of this morning resolving issues for customers relating to this power failure ranging from firewalls with corrupted configurations, failed VPNs, missing DNS servers, absent databases. In one data centre we had to power cycle the whole of our hosting infrastructure, routers, switches, firewalls, servers, etc to bring it back online in the right order. On another site we had to turn most things off because the aircon had not come back up and the room was like a furnace.
The power outage appears to have been total in some areas with even street lights and traffic signals going off. In one building we look after 30 staff working late were stuck inside the building because the electronic door entry and locks systems were off line and cars where stuck in the carpark because the barriers couldnt be raised.
I have had better Thursdays
