Continuing yesterday's node maintenance saga. In the end it looks like I didn't even hit 48 hours of downtime; Besu can sync from scratch pretty quickly and then everything went right back to normal. I've had much longer outages than this over the years, definitely learned to roll with the punches a little.
I did miss a block proposal, which stings a little bit, but I have enough validators that it's not like I missed my only chance this month.
