The connection check and leak detection page, previously at am.i.mullvad.net, has been moved to mullvad.net/check. A bunch of problems have been fixed, it has a fresh new look, and it's a lot faster!
But what about the API?
Don't worry! am.i.mullvad.net will continue to exist to serve the API endpoints such as am.i.mullvad.net/json. Only the web front-end has been moved.
