If its happening with every server it may be something at your end, try restarting your router/modem, just a simple off and on again should clear out any software conflicts.
IF that doesn't work, have you chjanged any MineCraft files recently, such as adding new mods and such?

I actually had that several times last night when trying to connect; if you leave and close it for a little bit and try log in, say 10 minutes later it seems to work. At least it has been for myself and a couple of others.
