Trouble with logging into minecraft...

I'm having a tad bit of trouble logging onto minecraft. Scratch that, I actually cannot log on whatsoever. My computer connection is correct, as is my internet, and I've recently checked too see that minecraft is having trouble with logging in, as well as with the multiplayer servers. I'd like to know why this is happening, or if you don't know why, I'm fine with that, however I'd like it to be fixed. It's been going on for an hour or so, and, as I currently lack a life, I have no idea of what to do other than sit here blank-faced waiting for minecraft to work. Can you attempt to fix this problem, perhaps? If not, I suppose I can wait, but my brain seems as if it is on the verge of explosion.
