When I went to look at why Mastodon users shouldn’t worry about Meta building on the ActivityPub protocol, I couldn’t — my Mastodon.xyz account had disappeared. The problem was DNS-related (it’s always DNS, remember Facebook’s massive 2021 outage?), and after a 23-hour, 59-minute break, the server’s back online. But it shows how decentralization can cut both ways — while this problem didn’t take down all of Mastodon, it left me trying to track down whoever runs my server to find out what happened.
