alpaca.blueAs @ricardo.bsky.social might put it, the infrastructure behind the Bluesky app is becoming more like a product (as opposed to a project). A natural evolution would be to charge Atmosphere app developers who piggyback on it and would like to have standard commercial SLAs and technical support.
AT Protocol Developers
Today we’re launching Bluesky Protocol Services, a new brand and website for the infrastructure Bluesky operates. And Jetstream v2, the best way for developers to use atproto at scale, now with network replay. atproto.com/blog/introducing-bluesky-prot…
