The Blizzard team behind the recent Starcraft Remastered project and other patches to Blizzard's Classic Games have announced a server upgrade/patch scheduled for today.
The following is a copy of the forum post:
Classic Battle.net services will be upgraded on Tuesday at 1000 PDT. We expect the maintenance to last one hour.
Specific Changes & Improvements
- Increased max channel size to 255
- Increased max clan size to 255
- Fixed clan message of the day
- Changed default channel to be based on language not region
- Fixed emails not being sent in correct locale for new accounts
- Resolved issues with Warcraft III ladder reset
Creating clans and arranged teams with more than 40 players in the channel will cause a disconnect from Warcraft III until the next client patch.
