Zero downtime is an ideal that you'd need a lot of investment for to achieve. I mean for 99.99999% uptime you'd already need to have a multi-server, multi-AZ, multi-region and multi-cloud setup and orchestrate data parity between those environments. That's not easy to set up and maintain.

Yes.

Tell that to all the companies that have to stop working when either of these sites go down because they've built their entire workflow on GitHub/lab being up.

Since zero downtime is so costly, maybe it's a better idea not to rely on the uptime of a third party?

You're wrongly assuming that your own service will have a better uptime.
