Due to recent changes in the administration of the freenode IRC network, all MetaBrainz IRC channels have migrated to the Libera.Chat network effective immediately.
The main channel names are all the same, #metabrainz, #musicbrainz, and #bookbrainz, though some special purpose channels were renamed in the move to better align with our project namespace (e.g., #brainzbot is now #metabrainz-bot).
Most of the MetaBrainz team will be around using the nicks you know already (e.g., bitmap, yvanzo, reosarevok, Freso, zas, …) but a few have had some changes: Mr_Monkey is now monkey and _lucifer is now lucifer.
Hopefully this will have minimal impact on users beyond having to update your IRC server in your client. If needed, Libera Chat provides a guide for how to connect to their network, including client specific guides for a number of IRC clients. They’re working on their own web client, but for now, Kiwi IRC can be used if you don’t have a local client running. For those of you relying on Matrix or Tor to connect: Libera.Chat staff is working on both of those and they should hopefully both be up within a week. Stay tuned on their Twitter: https://twitter.com/LiberaChat
As always, you can find information about our IRC channels and guidelines on our IRC documentation page. Wikimedia have also migrated to Libera.Chat and have written this handy guide which might also come in useful for migrating: https://meta.wikimedia.org/wiki/IRC/Migrating_to_Libera_Chat
As a last note (and I am admittedly biased being both former freenode staff and current Libera.Chat staff myself): it is my personal belief, as community manager, that freenode is no longer a safe network to be on for our users. The new freenode staff does not seem trustworthy, making policies to retroactively justify their own breaches of their policies, refusing to give a clear answer on “whether slurs, racism and transphobia are allowed on Freenode”, getting staff on board that were kicked from other networks for privilege abuse, and leaking staff-internal information (channel closure reasons) to non-staffers. I highly recommend disconnecting from the network ASAP and, if possible, overwrite your NickServ registered e-mail and password and possibly dropping your NickServ registration as well if you can and are able and willing to. If you have used your NickServ password for anything else, my recommendation is to consider that password compromised.
