Can't Connect

A few minutes ago I was just going to play on oasis for a bit, but the launcher only gave me the play offline option. I checked my internet, and restarted the game and nothing happened. I noticed that there are still people on the server, so I know that it's probably something to do with my connection. Does anyone know what the Problem could be? Thanks.

Mojang servers were being shaky. You should be good if you try connecting now.
If it still doesn't work try restarting your router.
