Me too. Unable to connect all day here on Malta.
Tried 3 restarts (Mac OS 10.14.1 Mojave) on a hard wired connection, as well as an attempt to log in using an iPad (with latest software update) - wirelessly (on the same network).
Thanks everyone for your patience as the team works to resolve this issue. Special thanks to @iworkms for directing everyone on this thread to Error: Lost connection to Codecademy where we’ll be updating everyone regularly until there’s a resolution. On a personal note, I understand finding time to study isn’t easy as it is, and this blocker is unnecessary difficulty, so we’re really working hard to remove this as fast as we can now.
