We are carrying out routine work on a pair of core switches on the morning of Wednesday the 6th of December. We do not expect this work to be service affecting.
We are starting this work now.
We have backed out of this work due to the overlap with this issue: "Some BT Circuits Dropping or high packetloss - https://aastatus.net/42586" We're not yet sure if this work was related to the outage, and we're still investigating. Further updates will be posted to https://aastatus.net/42586
