When you first started the client, your username and password is authenticated with the Minecraft.net server. This lets you start the game and play. Once you do this the first time, you can bypass this as long as you play offline.
Once you have started the game, when you select multiplayer and log onto my server, my server contacts a different minecraft.net server and once again validates your username and password. I can disable this feature, but it makes the server too insecure for my liking, so I won't.
The problem we are having today is that the initial authentication to start the game is failing, so we can't start the game except in offline mode, which means we can't connect to multiplayer servers.
