a 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

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.

Backing up Spotify
We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB). It’s the world’s first “preservation archive” for music which is fully open (meaning it can easily be mirrored by anyone with enough disk space), with 86 million music files, representing around 99.6% of listens.

Hubble is so cool, I highly recommend using it. I published a post yesterday that you can check out as an example.

hubble is live #atprotonyc
been thinking a lot about options for maintaining a sort of partial/sparse mst index over hubble’s mst-less record storage. and i have some ideas. (hubble doesn’t need this to serve sync.getRepo, bc star-lite’s mst reconstruction algorithm is fast enough to rebuild from scratch on demand)

tangled.orgThe fact that it's so easy to backup the whole network (also: hubble) is super strong, to be sure. If Bluesky-the-company got nuked, we know the current upper bound on how many accounts on their PDSes would be able to re-establish their identities today. It's 270. rob.leaflet.pub/3mr7vhdonuk2i
