Not saying it was a coordinated attack (per your edit), but anything popular is a prime target for various types of attacks, especially easier stuff like DDoS. But with every attack, the developers and various admins/owners of instances learn something new and how to mitigate it. So while it's annoying, it's just as much a blessing as it is a curse - better to patch things quickly than leave an exploitable hole open for who knows how long with access to who knows what.
I run my own single user instance, and it was down as well. Not sure why someone would target a single user instance. Not ruling it out, but it seems unlikely.
All instances using federation are publicly visible and it's simple to script attacking all of us.
However it's even easier to just attack Lemmy.world since almost everyone is there and it will have maximum disruption on everyone. People have centralized on one server. :)
But it's just some denial of service attacks right now. Eventually they probably get tired of it too. There is no point to it really.
The experience is pretty good except for discoverability of new communities. My Subscribed and All feeds are the same. I started with the official local development docker-compose file and massaged it into place for my setup.
Ah, yeah that could be problematic. Maybe I’ll hold off until accounts can be migrated, and port this one over to expand the content. Start subbing to everything I even tangentially like 😅. Tho maybe they will fix the discoverability issue - sounds like it happens kinda a lot.
