What's up at NTL/VirginMedia?

Seems to be a large-scale outage going on at Virgin Media ex-NTL, AS5089 in the UK. Lost service about 1600GMT yesterday to a wide range of locations throughout the country. Recorded phone message now saying several post code areas in SW London suburbs still dark, but status page shows lots’o’tickets open all over the country.

Anyone know what’s up?
