We have the first CHAIN SPLIT ⛓️‍💥 on plcbundle!

The reason is the (announced) deletion of invalid operations on plc.directory, which took place in the last few hours.

New initial hash (root): f743c3ae1e3f6023e89e492bce63b52a9ed03ee46a163c2f4a3b997eaf2aaf85

We apologize to everyone for the unavailability of atscan.net

The growth of Bluesky is unfortunately greater than we anticipated, and as an experimental project, we unfortunately do not have the capacity to maintain and operate this service at this time.

Real-time DNS check now works on each DID profile if the handle is set on its own domain.

Example (good): https://atscan.net/did:plc:ragtjsm2j2vknwkz3zp4oxrd

Everything you say and do here is "on the record", even more so than it normally is on the web, because all your posts are a) cryptographically signed, b) trivially replicable to other instances etc.

This is very much by design, and whether it's a good or bad depends on context

We just enabled account sign-ups again, so any outstanding invite codes can now be used to create an account.

Thanks for your patience!
We will temporarily be pausing Bluesky sign-ups while our team continues to resolve the existing performance issues. We’ll keep you updated when invite codes will resume functionality.

We’re excited to welcome more users to our beta soon!

My own PDS has faster response times than bsky.social 😎

This is mostly a geolocation thing, and also the fact that I only serve 1 user (me), but I'm still taking the W

We have the first chart! 📈 You can now see the response time graph on the PDS detail page.

Currently we are monitoring PDS only from Prague, Czech Republic (Central Europe), but we are planning to deploy also US and Japan node.

@atscan.net is so cool, and is immediately critical infrastructure 😅

really helpful for exploring atproto federation sandbox instances, checking if a PDS is live, where a DID lives, etc. nice!
