It would have been better if they communicated to us first. I don’t disagree that user signups should be spread over instances. We now have a link to https://lemmyverse.net on our signup page so people can check if another instance would fit them better.
Yes there is an issue with the Mlym container (old.lemmy.world), we have now stopped it because it also slowed the other alternative UI’s. We’ll troubleshoot this.
