How long is too long? - eviltoast

So, my instances have been offline for the better part of a month, and I haven’t had a lot of time or energy to fix the problem I caused trying to update to 4.2.1.

At what point is it not worth restoring an instance and best to just start from scratch? I don’t want to end up burning more domains and user names, but it’s a question since a lot of that stuff doesn’t get purged I don’t think from other servers, specifically the encrypted keys and identity information.

Just could use some help if possible, thanks folks.
