The domain registration date doesn’t tell anything about the amount of effort put in it. I usually register the domains of my side-projects only when I’m at 80% done; otherwise I would buy dozens of domains I would never use.

It’s biaised to show this without the dates at which features were introduced. A lot of the downtimes in the breakdown are GitHub Actions, which launched in August 2019; so yeah what a surprise there was no Actions downtime before because Actions didn’t exist.
