my thinking wrt hugs of death is that if one host is saturated, the content would be available at another host, such that it's not simply unavailable due to high traffic, but leaving that aside, I'm still unsure which party is delivering content to end users. If I host gifs at bsky.jazzyjackson.xyz, and my posts are indexed by some number of relays, and finally viewed by bsky or an alternate front end app, is that app mirroring my gifs to shoulder the burden, preventing traffic from hitting my $5 VPS? I always thought {bit,web}torrent would be a good fit for this problem of mirroring content among multiple hosts, but maybe there's a reason no one has gone down that road.
