okay and as promised, the bluesky PDS is officially open for returning users to migrate their accounts back!

hoping this lowers the stakes & gives folks the confidence to explore some other PDSs in the network!

All services should now be recovered!

AT Protocol Developers @atproto.com · 14d

An upstream network problem has been impacting almost all Bluesky network services for the past 3-4 hours. Posting and other public interactions are disrupted for many accounts.

As connectivity recovers, the firehose and other services will see large surges of events.

we just published an updated proposal for "Auth Scopes", and are interested in your feedback!

this is a mechanism for OAuth clients to request granular permissions to PDS resources. for example, only write repo records of specific types, or only authenticate to specific remote endpoints

OAuth updates for app devs!

we've rolled out some small changes to the DID PLC directory which make it possible to register new key types as verificationMethod entries, for non-atproto use cases.

(this does not impact the PLC rotation key mechanism itself; that is still limited to P-256 and K-256)

have fun building on PLC!

got a new proposal out about Sync 1.1, aka inductive firehose, aka cheap validating relays.

it is a long, low-level doc. doesn't directly impact folks unless they emit a firehose (eg, PDS and other repo hosts), or are doing full validation as a consumer
