Edge errors are the kind of incident that makes teams doubt everything at once. The origin looks healthy. Metrics are green. Yet users see intermittent failures, timeouts, or unexpected error…

Redirect loops are one of the most disruptive Cloudflare-side failures because they can look like “the site is down,” while every component is technically working. The browser receives responses, the…

IP reputation blocks are one of the most confusing Cloudflare failure modes because they can look unrelated to your application logic. Your requests are well-formed, TLS completes, and sometimes everything…
CAPTCHA prompts are rarely triggered by one “bad request.” In real traffic, they appear when Cloudflare’s edge becomes uncertain about a client’s continuity, intent, or risk profile. That uncertainty can…
Cloudflare session problems are rarely a single bug. In production, they show up as patterns: cookies that seem to disappear, pages that alternate between variants, and redirect loops that never…
Cloudflare WAF blocks are especially painful when they look inconsistent. A request pattern that worked yesterday can start returning 403s today. One worker is fine, another hits a block. The…
