Probably a two hour window to give me time to get things done. There may be an upgrade to lemmy 0.19.11 however that requires some modification of ZippyBot due to changes in the new version.
There will be downtime while the server is restarted, however hopefully this is brief.

I think it is more of a limitation of activitypub and DNS. Any work around for this would be cutting out the original server which would likely be a major security risk.
Honestly what it should do is warn users when a instance is down and maybe even lock the community if it is without a local mod for to long. Maybe it could warn after is it down for a hour and then lock after 6 hours.
