Configuration file size limits causing cascading service failures

9/10 Critical

A configuration change caused a file to double in size, exceeding Bot Management's upper limit, resulting in HTTP 5XX errors that cascaded across dependent services (Workers KV, Access, Turnstile, Dashboard) into an internet-wide outage.

Query: “What are the most common pain points with Cloudflare for developers in 2025?”4/8/2026

Cloudflare engineers implemented a change that caused a configuration file to double in size...Bot Management has an upper limit on the size of its configuration file...a single failure in any one can have a cascading effect on the others.
