It appears that the east coast mainline has been almost completely down for much of the afternoon and all evening due to a foil balloon interaction with the overhead wires at Huntingdon.
I had a quick read of a technical update sheet at KGX that was laying around and it seemed to be pointing to a non-trivial fix due to problems with some of the downwires (?)
