It's the server that can't keep up for some reason. Bad connection maybe, or something like that.

Speaking of which, I just tried again and it said "Disconnected by server -- outdated client!" 

Then either your version of Minecraft is outdated (unlikely since it updates automatically) or the server is obsolete, and whoever is running it needs to download a new version from the official web page.
