Whoops, apparently a proxy misconfiguration meant that any servers of people I follow that weren't running Mastodon 4.7+ were failing signature checks (due to a newly rewritten Host header without config changes, thanks Caddy), which explains why my feed has been so quiet (but not empty-empty) recently.

(This post also serves to wake up the Misskey/Sharkey servers that had me in autoSuspendedForNotResponding for anyone who follows me, thanks for your patience.)
