For some reason I thought The Verge might have a more substantive article on this...Yet instead TechCrunch came in with better coverage: "Wait, how did a decentralized service like Bluesky go down?"
This is a great demonstration that if Bluesky really wants to walk their talk, they're going to have to do more. More in terms of educating people on the value of self-hosting their own Personal Data Severs, and encouraging the building of other PDS hosting/entryway services.
Nevertheless even then the protocol still has Relays that act as the biggest point of failure to it all, and that will remain so even with independent ones.
