npub1ztxcrpp7m7japy6nrzqwy72v6g5alnqaxuda8cm9m63ffnfe0c4q67t572 (npub1ztx…t572) Stefano BSD Cafe (snac instance account) (npub1fza…qg7t) exactly. All the known servers will contact me and pull the image. The same is happening with Mastodon, if not using an external S3 media server. But on the BSD Cafe I've set an external jail, behind Cloudflare, so media get cached almost immediately.
Maybe I'll study a similar solution here, even if I don't plan to keep the snac instance here, but I'll move it back to the VPS at the end of the tests.
