If anyone wants to see why this specific did:web couldn't log in. TL;DR bsky handle resolver returns the wrong DID from a stale index. Now I use the authoritative source.
bsky.social returns a did:plc that *used* to be associated to that handle, which is now pointing to a did:web

I’m seeing lots of people having problems with Bluesky and PDS issues in general today. Then saw this from a bsky team member. There’s a very good chance this was the cause but I’ll keep looking.

Some ideas for your next post: embed your favorite song, a social media post, your own musical writing, a Mermaid diagram, an interactive graph, or hide spoilers!
