By 2021, Blizzard had purged all versions older than v1.13c for Diablo II and pre-1.27 for Warcraft III to force users onto the new CDN (Content Delivery Network).

For many users, the appeal of local FTP servers was the potential for intranet speeds. Because the data was traveling within the Bnet network (locally) rather than going out to the global internet, the transfer speeds were often blazing fast—limited only by the user’s plan (e.g., 100Mbps or 300Mbps fiber).

In 2021, tech-savvy users set up local FTP servers to share large files: HD movies, game installers, and software patches. This allowed neighbors and fellow Bnet subscribers to download massive files in minutes rather than hours, bypassing the congestion of international gateways.
