I don't usually like to post news unless it's fact, but, whatever. In a forum over at MythMaps there was a post today from Clem, one of the bosses over at The Mill, when asked about the future (?) of the site:
Based on email conversations I had this week I'd say I can safely say "no".
If fileball.net would ever show back up it would likely only be as an example of what was built technically and would not include downloads.
Just to much of a hog of services and $$$$ for what was received back at this point.
Sad to see it go.
As a side note, the mainpage for Fileball still shows the last post from 4/30/02 stating that the network will be back soon.
