A general call-out to #fediadmin about whether they have been experiencing issues with site availability, specifically an on-again off-again bot wave that crawls publicly-available ActivityPub data at a rate so punishing that it overwhelms my server.

We had to turn on "I'm Under Attack" from the CF dashboard, but that comes with some not-so-nice tradeoffs (including blocking all automated crawlers, even the good ones.)

I initially thought someone just didn't like us (community.nodebb.org, actually), but now we've received reports of it happening to another NodeBB, and @silverpill@mitra.social's mitra.social is down for the count currently.

Admittedly, that last one could be unrelated.
