Battle.net Server Upgrade - 14 August 2018

Blizzard has patched Classic Battle.net again.

The biggest change this patch is the restriction of legacy Diablo II 16-character CD-keys. Now in order to log in with Diablo II and/or its expansion pack, you will be required to register your CD-key on Battle.net with your Battle.net account, and then use the new 26-character game key instead.

Hi All,

Servers will be upgraded on Tuesday at 10am PST. Expected downtime is less than 1 hour.

Notable changes:

• [D2] Network migration for inbound server traffic to increase performance and reliability
• [D2] Disable the use of claimed 16 digit keys to prevent abuse
• Improved service monitoring and alerting

Thanks, Classic Games
