All I see is a blue void (tried two browsers) - do I have to click something?

Looks like it starts at 0,0 - zoom out on the map to find land

If your browser doesn't have your location for whatever reason, most maps will drop you into lon 0, lat 0, which is South Atlantic Ocean west of Africa.

I tried a bit of moving and zooming, but not enough I guess.

I really hate this, not that it's a bad default for location, but that it's a bad default for zoom.

Strava (running/cycling gps tracking app) has default zoomed all the way into San Francisco, so if you want to find anything you have to zoom out first. What they might thought is a little fun gimmick is annoying as hell.

I had to select a Provider on the left side before the masts starting showing up.

it gave me a very zoomed in view of what I assume is Null Island (GPS coordinates 0, 0). Zooming out several times eventually reveals map elements.
