[Question] resilience to downtime (lemmy.sdf.org)

I'm looking for input on how well Lemmy responds to occasional downtime of up to a few days, specifically regarding how federation recovers after such an event.

Basically looking to know how amenable it is to selfhosting via reverse proxy from dodgy setups which are the best some of us proles can manage. I try to run some services where I can but my situation inevitably results in an event or three per year, on average, with some days down.

Outgoing federation actions are kept for 7 days. So if your instance is down shorter than that it will catch up with everything.

Good to know, thanks!

It'll tolerate a few hours no problem, mine's been down for a bit over 24h and caught up fine.

I think it marks instances as down after 2-3 days, but I'm not sure if it'll resume once it comes back up at this point. I think if your instance reaches out it might start pushing events again but it could also result in dropping the previous days.

Useful info, thank you. Once in a great while I have outages of a week or a little more, usually because something breaks when I just can't rally the resources to fix it right away. Ideally this would never happen on infrastructure used to run an instance, but my hope is that various fedi platforms will be resilient to downtime on the order of 7-14 days before they entirely give up. I think it would be helpful to small and/or broke instance operators, and I would like a fedi with lots of little instances. :)
