Not that I’ve ever seen, that would kinda be a waste of resources of the lemmy servers.

Federation is only one “level”. The origin sends it to all the other instances, they don’t relay it along.

Just pop that url into the search of another lemmy instance. If it has a copy, it’ll come up.

Ie: https://lemmy.ca/search?q=https%3A%2F%2Flemmings.world%2Fpost%2F41938713&type=All&listingType=All&page=1&sort=TopAll&titleOnly=false

I’d also suggest throwing more cores at it than you think it needs, and increasing the nic buffer sizes. This is what finally solved the random 1-2 minute outages I was seeing on lemmy.ca, turns out we were somehow saturating the queues even at relatively low traffic levels. (these issues might be specific to our model nic)

Finally, make sure hardware offloading is disabled, and your CPU type is set to host.
