Remember when the megapack was released? It seems it was accidentally released a little early, a Friday night if I remember. I was one of the first ones to grab the DL and post pics of them to the atari forum.
Then, all of a sudden, it was down and you couldn't get the megapack from the atari site. It didn't come back till Monday, when it was "officially released".
I think that little incident shows that atari, gamespy, whoever, doesn't do everything correctly all the time, and the little kerfluffle that is currently happening, is just another example.
I always though gamespy only ran the logins/friends list thingy. I've seen an error trying to log in which said something to the effect of no login server found, or some such such do-daddle. Good to know, if atari keeps the TDU1 servers up.
