Diablo III Chat Channel Bug Under Investigation

Chat channels are not populating properly, which may be fixed in Tuesday's maintenance

The in-game chat channels within Diablo III are not placing enough players within each channel. The bug is currently being investigated by Blizzard's systems administrators, and it may be fixed with the server maintenance on Tuesday, which is scheduled to last for 8 hours.

Ever since the lengthy server maintenance on last Tuesday, July 16, the chat channels have not operated properly. In that previous maintenance, new equipment was put in place in the Diablo III server structure. That caused an issue with the chat channels populating up to full, before a new chat channel is created. Chat channels right now often reach a maximum of around 20 people, instead of the 99 that they are supposed to go up to.

This was explained in posts by the Blizzard technical support staff in the EU and US. The issue may be resolved by the upcoming Tuesday maintenance. The following blue posts detail the issue; they will automatically be updated in this news, if more information is posted in that thread.
We're investigating right now - I just checked with Omrakos (who was quoted earlier), and we're finding the number of players in the channels is not consistent with what is expected with the games that are being played. The systems administrators have been notified and I'll do my best to provide an update when one's available.

Thanks for your patience everyone!
Update 7/18: Our systems engineers have located the issue that has made it difficult for games make to find populated channels when joining chat. Although I don't have an exact ETA for when this will be resolved, please know that we are currently working on this and it may even be as soon as the next maintenance period when this has been taken care of.

Thank you to everyone for your understanding, and your patience! On this glorious Thursday, you have the blessing of Araxom that the Loot Goblins will treat you kindly and that your enemies will run in fear before you!

Why did the devs change anything about chat channel population in the last maintenance? O.o

The black magic which is server maintenance is sometimes beyond even my powers of understanding. Basically, as I understand it - new equipment was put in and this kinda/sorta changed how the system looked at the grouping of chat channels. The affect to the chat channels wasn't something that was intended - but you all were right, something (is) definitely up. So, we've confirmed that and are currently working on resolving it.

@Skillol: Good call out - that's been resolved. As a side note, to everyone, if you would like to notify us of exploits, please don't do it by pasting a link here in the forums. Instead, you can alert our administrators through hacks@blizzard.com

The server maintenance for Tuesday will start at 3:00 AM PDT and is scheduled to last for 8 hours.
