Stefano BSD Cafe (snac instance account) (npub1fza…qg7t) The Real Grunfink (npub1p77…0jxq) Update: I've noticed it also happens when opening my user's page (https://snac.bsd.cafe/stesnac). It's slow as the snac server sends tons of calls to the Mastodon webfinger instance.
It wasn't so clear before as the Mastodon and snac servers were on the same VM so the requests were local.
