Both were down for me before, they seem to be up right now but just made this account on Lemmy.blahaj.zone (Henry is the name of my actual blahaj lol). It’s probably because of the traffic influx from reddit refugees from the absolutely disastrous spez ama (where he doubles down on everything and doesn’t apologize at all). Allegedly they’re trying to suppress Lemmy mentions but I guess it’s not working well enough lol
A good problem to have although long term we’re going to have to figure out how to deal with these spikes in traffic.
Re Mastodon: Tbh I’m not sure. I’m also a reddit refugee and have been exploring different fediverse services. I think how mastodon implements it is as a sort of “authenticated redirect”. Not to sure on how ActivityPub supports one account controlling another account on ActivityPub. Maybe could be implemented as a sort of keyring, where the most recent account on the newest instance has tokens for each of the past accounts on the old instances so that their posts can be transparently modified by the most recent account?
Or maybe this is a non-issue and people can just make new accounts on different instances.
