One note for anyone who decides to use this tool: I recommend running it several times to make sure all relays are properly synced.
quotingI made this a little while ago as I was getting zaps to an old address, but just pushed up some changes. It's just a python script that queries all queries all online relays, identifies relays with old events, rebroadcasts the latest verified kind 0 event to those relays and reports the status of the rebroadcast.
