Bringing Bridgy's backfill back! (and unblocking a big Bluesky broadcast 👀)
Introducing Hubble: A Public Mirror for the Whole Atmosphere - AT Protocol
Bluesky is providing a grant to the creator of Microcosm to build a full mirror of public data on the Atmosphere to help make the network more resilient.

Launches: Credible Exit, Bridged User Notifications, & Fediverse Re-Bridge
Today, we’re announcing a bunch of migration features and improvements across Bridgy Fed and Bounce. The main goal we had with these latest updates was to make it so people can migrate in every direction possible across ecosystems while reducing the friction of migrating while using our services.

FOSDEM 2026 - How to level up the fediverse
The fediverse isn't done! Or, at least, that's the opinions of ActivityPub co-authors Christine Lemmer-Webber and Jessica Tallon! Discover how we could improve the fediverse with ActivityPub-compatible improvements to add more robust and secure communication/cooperation patterns, decentralized storage and identity, etc! Plus: how Spritely is starting to apply its technology towards exactly this goal, bringing Spritely's next-generation internet tech to the fediverse!

blog.anew.socialIf you've backfilled the network before, you probably noticed the 65k bridged accounts you couldn't sync. …until a week ago! Bridgy Fed's `getRepo` is now open, and served by Hubble!

Today, Bridgy Fed begins expanding beyond microblogging, starting with long-form. If your Atmosphere (Bluesky, Blacksky, Eurosky, Northsky, etc.) account is bridged, all of your @standard.site publications and documents will bridge over to the Fediverse and the web 📜↔️📃 1/4 🧵
Long-Form Comes To Bridgy Fed
blog.anew.sociala neat thing about hubble is that you can get a point-in-time* snapshot of the whole network. vs doing your own backfill crawl, which will give you samples spread over a >24h period any researchers who want this, feel free to reach out

"The end result of all of this is that we grew from 2k users to almost 150k, added a ton of heavy new functionality, and still managed to optimize and cut down costs from $.15 per active user per month to just $.03 or so." - @snarfed.org breaks down all the work he's done to optimize Bridgy Fed 1/
