Many of our TalkTalk ADSL and FTTC lines dropped at 10:08. Most lines reconnected by 10:11, and the remaining by around 10:18. Cause is yet undetermined, we're awaiting updates from TalkTalk. They did report a 'network flap' that affected a smaller number of lines at 9:52, but we're not sure if these two sets of blips are related.)
Further update: TalkTalk do say that that drops were due to link flaps on fibres between their datacentres.
