Internet Partially Down?

So I was just about to put up a fresh post and I noticed some of the sites I needed to go to aren't loading. I am online - I'm on AIM right now and I'm posting this - so I have a connection. MySpace, NetVibes, Blogger, and Gmail are working just fine for me. Well actually, MySpace is working fine except some peoples pictures aren't loading. This is all really fucking wierd, can anyone explain to me why this is happening?
