Kiwi Farms is back on an alternate domain.
Posters in the Keffals thread believe the fake bomb threat was to blame for Cloudflare’s reaction. The account which made the post barely had any other activity on the site. The post itself was removed quickly by moderators. If it’s true that an obvious fake bomb threat which was swiftly removed was the cause for this action, Cloudflare has some hard explaining to do to its remaining customers. Fake anonymous posts and an ideological Twitter mob can apparently DoS your entire operation with Cloudflare.
If the threat was something else, I and other customers would love to learn exactly what it was.
