This actually affected myself, some sites like wmw where ok and others just failed to load at all.
http://www.bbc.co.uk/news/technology-28071423BT has apologised after "many" users in the UK experienced problems recently connecting to the internet, but says the issue has now been resolved.
Users complained they were unable to connect to some websites - including social media, banking and shopping sites - as a result of the problems.
BT said it was unable to say how many customers had been hit, but issues were reported in various parts of the UK. "We're sorry for any trouble this may have caused," a BT spokesman said. The firm, which has about seven million broadband subscribers in the UK, said it was still investigating the incident.
It was probably just GCHQ testing out a new web off-switch mechanism as used by despots worldwide
This new "unknown cause" does make a change from the normal metal thieves routine we hear, but lets be fair the infrastructure BT operates is normally working fine and has done so for many years bar a minor hitch here and there across many years now so I wont tease them too hard
