(CNN) -- London airspace is open but traffic is being restricted, the UK-based global air traffic management company NATS said Friday.
"Airspace is open. We're restricting traffic volumes in accordance with capability we currently have in our system," it said via Twitter.
The update came a short time after the European air traffic control network, Eurocontrol, said all London airspace was closed because of a computer failure. It said no flights would be accepted in or out of London until 7 p.m. (2 p.m. ET.)
A spokeswoman for NATS told CNN that a "technical problem" was causing the disruption.
