Public pictures and videos go to blossom.ditto.pub first, then primal, nostr.download, nostr.build.

A 2026-09-30 benchmark (4 MB mp4, 110 KB jpeg; upload then fetch, twice):
ditto took the mp4 in ~0.6 s and serves from ~120 ms; primal ~1.5 s;
nostr.download ~1-2 s but rejects a JPEG with data after its end marker
(motion photos); blossom.nostr.build ~5 s with ~600 ms first byte.
