Air traffic control company Nats has issued a full statement on "technical problems" at its Hampshire control centre, which has caused delays to thousands of flights.
We are experiencing technical problems at our Swanwick control centre and we are working to restore full operations.
This has not resulted in the closure of UK airspace or the suspension of all flights in or out the UK.
However, to maintain safety, we are restricting the number of aircraft flying across the south of England and those taking off from airports. We regret any inconvenience this may cause; however, our first priority will always be the safety of the flying public.
We are taking every step to restore services and have contingency plans.
