IOMart
They may be part of IOMart and their website (HostingUK) certainly makes much of the 10 data centres , but they actually operate out of just two data centres.

The noise about ten datacentres is just interesting since they actually only use two of them.
This time they managed to have in place a emergency answering service who had the same level of information available on Twitter and various blog sites, so lesson learned there.
The last thing i've heard from them is that they are ordering another line, but the Twitter feed was interesting in that it mentions staff working from wednesday on issues, so that was probably Fibre 1 cut , with little action until the Farmer cut the Fibre 2 on Friday. Probably not the 2km dash by the Farmer in the middle of the night.
I started asking about moving Data Centres but then re-read the two data centre weasel words so now i'm having to look round for big boy geo redundant hosting.
