Happening now - Heathrow/Gatwick Ops suspended due to ATC radar failure

https://www.thenationalnews.com/news/uk/2025/07/30/london-airports-suspend-after-radar-outage/

Flights at London's major airports were grounded or diverted on Wednesday after a significant air traffic control fault hit air traffic control.

Radar systems went down as the authorities investigated a potential glitch in the systems serving the London Control Area, according to Eurocontrol.

Heathrow and Gatwick airport said take off and landing had been suspended. Within minutes passengers were reporting knock on effects of widespread delays and cancellations affecting flights.

This is apparently across the UK according to the National Air Traffic Control Service- Birmingham, Manchester, Edinburgh, Stansted and East Midlands all report no outbound flights- from BBC News.
As of 1635 the system is restored according to NATS but it will take time to recover.

skunklet1771 If you want UK news in the US, add the BBC app to your phone. You can get live reports.

There will probably be mention of this event on the national evening news.

Yeah, former US military air traffic controller here; the US has outages all the time, you just don't hear about them...
