This flight path is not on the Coverage Map map.
The FlightAware ADS-B Coverage Map has just been updated an hour ago (UTC 5PM, by the way this is also unusual. The map was always updated on Monday at UTC 9 AM).
Now the MLAT map looks like this in different browsers.
The maps are updated once per week and only include data from the most recent week (as noted on the web page). It does not show cumulative coverage for all time.
There will come soft rains and the smell of the ground,
And swallows circling with their shimmering sound;
And frogs in the pool singing at night,
…
And No change for the better happens. The weeks pass, but the artifacts on the map do not disappear.
Different browsers, different computers, different providers…
