Our team received a report of intermittent app outages at about 11:40pm PDT on April 15, 2026. They worked through the night to mitigate a sophisticated Distributed Denial-of-Service (DDoS) attack, which intensified throughout the day.

That was probably the most widely reported outage in recent times. @reports.blu.ski

Attention PDS devs! We merged a lexicon change last week increasing the max image upload for Bluesky posts from 1 MB to 2 MB. This rolled out to our PDSs instances last Friday. We'll begin enabling this in the Bluesky app soon. If your PDS implementation is still validating at 1 MB, plz update! ✌️

the firehose if everyone was just DMing you

Reposting since we are talking about it again… sri.leaflet.pub/3maltcnnbqs2n

did it. direct-from-object-storage backup restore for rocksdb. this should make it *much* less painful (and way faster) to launch a new constellation instance from the public backups.

Pleased to announce that an Authenticated Transfer Protocol (ATP) working group has been created at the IETF! Grateful to everybody who participated in the BoF and chartering process. Details on next steps and how to get involved inside. atproto.com/blog/kicking...

🌊 🌊 🌊 Today, we’re launching social websites, a new kind of online destination. These blend posts from Bluesky, Threads, Mastodon and more, plus YouTube, podcasts and your favorite publications to create community sites based around the things that matter to you. about.surf.social/surf-launche...

Q1 update: can confirm. got worse. 🫠 @goals.garden @firehose.network @firehose.stream and the big one: @atproto.at v2

Hey y'all! One of the things I took from #AtmosphereConf was that there's still a hole to fill to make it easier for users to back up their identities and that something like a mobile app may do that. So if you're interested, please take a bit of time to answer the questions to help shape that app.

On March 29th, we held an in-person meeting to check in with the community and discuss potential updates to the standard.site spec. A huge thank you to @cozylittle.house for putting together a detailed summary of everything we discussed. leaflet.pub/p/did:plc:ky...

that was awesome! huge thank you to everyone organizing #atmosphereconf

Sri is at #AtmosphereConf and launching Taproot - a super-powered all-in-one AT Protocol Explorer. Browse PDSes, export repos and download blobs, stream live data, and so much more. Learn more here: sri.xyz/projects/tap...

next #atmosphereconf (or even this), I need an option to get this as part of remote ticket.

Created a feed about @attie.ai on attie bsky.app/profile/sri....

Hey guys, I think this @pfrazee.com guy gets it! No, seriously, made my day 🙇🏻‍♂️ Say it louder for the people in the back: People, not platforms!

1/ Today, we’re excited to introduce Attie, currently as an invite-only closed beta. Attie is the first agentic social app on atproto. It’s something completely new—an experiment in making building on the protocol more accessible.

Paul mentioned Taproot, which @sri.xyz just launched at the conference with an all new set of tools for working with atproto, in his keynote. Check out everything here

slides for my talk (now-ish) if you want to follow the small-text (or get spoilers)

200-dollar-plasma-screen-tv.firehose.stream it's firehose friday #AtmosphereConf

glad people are finally taking climate seriously and having a whole conference about the atmosphere this weekend

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 🧵

excited to announce our new platform for content moderation and community management at scale. this replaces ozone for us. built by @rishkebab.blacksky.team hand in hand with our T&S team.

Thrilled to be working with @bad-example.com, whom you know from the excellent @microcosm.blue tools, on making the atproto network ever more resilient atproto.com/blog/introdu...

here it is folks! lots of details to still nail down, but this is roughly where our heads are at for the design of a permissioned data protocol give it a read and let me know your thoughts!

okay, officially launching the first (alpha) version of atmo.rsvp!

well: a first backfilled lightrail

buckets are out, spaces are in

Sound on. Aether OS Alpha is online. aetheros.computer #atproto #atdev

Big day! @jay.bsky.team will remain deeply involved as CIO and I'm personally excited she's dedicating more time on the future of atproto. I'm also very pleased that @toni.bsky.team is joining us as the interim CEO. He seems like a thoughtful, experienced person who cares about the open internet.

Some personal news: I’m transitioning from CEO to a new role as Bluesky’s Chief Innovation Officer! I’m excited to welcome @toni.bsky.team as our interim CEO. More here: bsky.social/about/blog/0...

We're so excited to support @thisismissem.social's work bringing FedCM to the open social web! atproto.com/blog/working...

Ok, ready 🌟 pulsar.feeds.blue :) (I've temporarily hidden atproto.africa because I got some weird numbers from it right now, will investigate) I have a few more ideas for improvements, but I think it should be useful already. #atproto Let me know if I should add/update anything.

First 1-hour pulsar measurement 💫

today, we're announcing our €3,8M ($4.5M) seed financing round, led by byFounders with participation from Bain Capital Crypto, Antler, Thomas Dohmke (former CEO of GitHub), Avery Pennarun (CEO of Tailscale) among other incredible angels. read more on what's next: blog.tangled.org/seed

Business models in the atmosphere?!?! Let's talk about how atproto and standard.site can move social media away from enshittifying, attention-based business models towards intent-based business models that better align revenues with openness and interoperability. jshaked.leaflet.pub/3mfrgv2aezc2g

It's been almost one full fortnight since our last one, we're doing office hours again this Friday. And we're bringing special guests to talk all about building on atproto. smokesignal.events/did:plc:lysq...

Attention Gophers! There is now a feedgen starter repo in Go! Very minimal and tiny Go build something cool! github.com/bluesky-soci...

The atmosphere has some great labelers that do an amazing job of moderating. But as PDS admins, we do not have a great solution to use these amazing resources. So I created label-watcher. It subscribes to multiple labelers and notifies you if a user on your PDS gets labeled by a watched label.

full-network atproto relay on a $4.20/mo VPS demo.tiny.hose.cam still getting connected to PDSs, we'll see how long it survives...

After notifying all our CFP submitters, we now have a full list of speakers and talks!

the new HA config is live. slingshot now has two big host instances, with passive (effective!) DNS load balancing/fallback. zero-downtime deploy worked smoothly to get the primary instance updated today! microcosm infra is 100% community supported– github.com/sponsors/uni... ko-fi.com/bad_example

We've released a self-hostable reference implementation of a PLC read-replica service to make the Atmosphere ever more decentralized. @retr0.id has details on what this all means. atproto.com/blog/plc-rep...

We've been hard at work on a new website with new guides, better docs, more translations, even our very own blog. We think it looks pretty sharp, too. It's now easier than ever to just build things with AT Protocol. atproto.com
