Incident Report for Cloudflare

Resolved

Between 18:20 and 23:10 UTC today (11/29/2022), we saw random prefix attacks for some domains and queries were refused because of automatic attack mitigation.

We have temporarily disabled automatic attack mitigation on the affected domains everywhere, and we are looking at improving detection of valid names while still blocking random prefix attacks.
