At the moment we're kind of like sitting ducks until something happens again IMO. I recall reading something on the Techlore forums about someone helping out with the server maintenance for lemmy.one, so maybe that's been happening in the background?
An update from him would be nice at least though.
If I was to jump to another instance it would probably be dbzer0 or programming.dev
Feels like it sometimes. I mean hell, the last time it broke I had to email Jonah to even get him to come look at it... to think it's managed to run this entire time with zero interaction or maintenance is scary.
I don't know about abandoned, but I joined it during the migration and mainly just for a home for my account. I rarely see much content on this instance, but that's also kind of okay.
