Wait, how did a decentralized service like Bluesky go down?

Bluesky, the decentralized social network, went down for roughly an hour on Thursday evening, leaving users unable to load its app on web and mobile. The company's status page attributed the outage to "Major PDS Networking Problems," with a first message posted at 6:55 p.m. ET and a fix being applied by 7:38 p.m. ET. On Friday, Bluesky CTO Paul Frazee confirmed that its personal data servers were hit by DDoS attacks, while other PDSs were not targeted. Frazee said the current theory is that the attack was an accident by a third party, and its source has not been identified.
