Isn’t this one of those situations where, if they can’t find or resolve the IP to a geo location they place it at a random place, usually in the middle of the ocean? I recall there being more issues like this with different companies.
This an odd case of dereferencing a NULL Pointer. Some Apps default to this valid physical location (It has become a tourist destination for the brave or foolish) leading to strange directions and distance calculations.
If need to have a default make sure it is not a valid location such as using +91 or -181 (out of range values).
If you look closely, it strongly resembles another island: https://www.trueachievements.com/game/Myst/walkthrough/3
