It was a little while ago, but it was 3 production servers running with the mirror backend, with a dirty-bitmap [0], and a complicated routing setup (which could hold packets instead of dropping them, depending on their importance). I didn't really have anything to do with the routing though, so I can't say much.
I'd probably use COLO if I was to do it again today.

I wonder what sorts of scenarios would benefit from using this instead of any of the dozen distributed database architectures it seems are out there. Incidentally while poking through https://www.qemu.org/docs/master/system/invocation.html https://www.qemu.org/docs/master/system/invocation.html I noticed that there are some COLO-related options in there, which is a bit exciting.
