Nice thing is you skip port forwarding entirely, which matters a lot if your ISP has you behind CGNAT. Curious how people handle uptime though, since a hidden service going down isn't something you notice until someone tells you.

Agreed yeah. Mine has been up with no issues so far for ~half a year.
