Original story follows:
The airspace above London has been closed due to a computer failure. The situation was first announced by Eurocontrol, the European Organisation for the Safety of Air Navigation:

National Air Traffic Control (NATS) then confirmed that a technical problem at its air traffic control center in Swanwick is the heart of the problem.
