That's a default message that doesn't mean what it says.
Obviously there no updates ever again, and they won't touch our server unless it was to update al.

Some networks can block game servers and or video but still allow you to use other sites selectively.
I get that message when I'm connected to my employers network. I can chose to disconnect from that free wifi, and then be able to log into games.
I've heard some dorms and other places do similar things.

Might not be that, but just throwing that out there.
