Federation is eventually consistent, but when we’re talking practical terms, how long is too long for a node to be offline?

I suffered a bit of a data loss and while I was able to recover my mastodon instance within 2 days, lemmy took me a week and I don’t see anyone spamming the inboxes again.

Should I expect that other servers effectively defederated me and should I resubscribe to my communities or I should give it a few days?
