Too bad it's a rather shitty JPEG that's blotchy in the more uniform "white" areas. I've been able to compile a map from the png tiles for the earlier versions of this map.

It uses mapbox.js and tiles have URLs like this one: https://tiles.telegeography.com/maps/submarine-cable-map-202...

https://dezoomify-rs.ophir.dev/ is helpful.
