- The downtime was not relay level, but it was a PDS level. So the point is moot already.
- Because it was decentralized at the PDS level, the outage did not affect anyone with personal PDSes, which contains the data that you care about.
- Even if it was the relay level, relays aren’t centralized, anyone can spin up another relay (because everything on the relay is derived from PDS data). It’s just that it’s going to be pretty expensive and consume much resources. Which is a fair point, and might be argued that the network currently has a single big point of failure, but that doesn’t mean it’s centralized.
And then people now start arguing that the fact that BlueSky-hosted PDSes went down at the same time is now another proof that BlueSky is centralized?
That’s like arguing that Gmail can go down and all @gmail.com mail addresses won’t work, so email is centralized. Or AWS can have an outage and all AWS-powered websites will break down, so the web is centralized.
One can say that there’s a single big point of failure (which the BlueSky LLC is, just like AWS, Gmail, or the mastodon.social instance in the case of Fedi), but that doesn’t make the whole service centralized.
