No flights in UK airspace

I did the Flight Tracker for London Heathrow and no flights appeared.

Can anyone explain why?


Just checked and many flights showing.

You are checking EGLL right?

I looked at some airports there, and they all worked for me…

This was resolved.

Any details on why it happened?

Swamp gas. That’s my story and I’m sticking with it.

Actually it was a transoceanic connectivity issue that lasted about an hour.
