Key points at a glance

• Large Cloudflare outage on November 18, 2025 made major sites unreachable for hours
• Cause was an internal database permissions change that broke Bot Management workflows
• No evidence of a DDoS or external attack according to Cloudflare
• Traffic recovered in stages, with full restoration later the same day
• Event shows the risks of centralization and single points of failure on today’s web

What took The Techbull offline

If you tried to visit us and saw an error page, you were not alone. On November 18, 2025, a widespread Cloudflare failure pulled a big slice of the internet into the dark for a few hours. We route traffic through Cloudflare for security and performance, so when their network stumbled, our pages did too.

Cloudflare’s CEO Matthew Prince explained what went wrong in a detailed note on the Cloudflare blog. The outage stemmed from a bad database permissions change that allowed invalid entries, which corrupted a critical file and tripped up the company’s Bot Management system. That single mistake cascaded across systems and caused global errors.

Who was affected across the web

When Cloudflare sneezes, the internet catches a cold. The disruption rippled across publishers, SaaS tools, ecommerce platforms, and social feeds. As TechCrunch reported, services like X and ChatGPT were among those showing errors during the window. Coverage from Techi underscored a familiar theme. Much of the internet now hinges on a handful of infrastructure providers.

This is the same concentration risk we have tracked in other incidents, including big tech dependence after prior cloud failures. One subtle change in one system can create a domino effect that is felt worldwide.

Was it a cyberattack

Many of you asked if this was a DDoS wave. At first glance the scale did look like an attack, especially after recent campaigns like those that hit Kenya. Cloudflare later said the root cause was internal, not malicious activity. The failure showed how a routine update can create unexpected knock-on effects in complex systems.

How Cloudflare restored service

Once Cloudflare isolated the problem, engineers rolled back the offending changes and restarted impacted services. Prince said core traffic began recovering around 14:30 UTC, with full functionality reported by 17:06 UTC. A public post incident review was promised on the company blog with steps to harden change controls and reduce blast radius for future incidents.

External reports, including TechCrunch, noted Cloudflare’s commitment to additional safeguards. That usually means tighter guardrails on configuration, stronger canary rollouts, automated rollback criteria, and more aggressive chaos testing before changes reach production.

What we are doing to stay resilient

We rely on Cloudflare for security and performance, and we are grateful for the quick recovery. Still, incidents like this push us to build in more resilience. We are reviewing failover options, cache strategies that degrade more gracefully, transparent status messaging, and better real time dependency monitoring. You should not have to wonder what is going on when the internet hiccups.

If your business depends on web revenue or uptime, you might consider real time analytics that flag anomalies across traffic, latency, and third party health. Platforms such as Databox can help teams unify signals in one place so they spot issues sooner, you know, before customers do.

Recommended tech

We use a mix of observability and security tools to understand what is happening under the hood. For a practical starting point on performance dashboards and trend tracking, Databox is a solid option that is easy to roll out and easy to share with non engineers.

The outage also nudges a broader conversation about personal security. This event was not an attack, but plenty of threats out there are. Strong identity protection and fraud monitoring help lower the risks.

Recommended tech

To keep your own digital life safer, consider an all in one security service. We recommend Aura for identity theft and financial fraud monitoring along with device protections.

Why this outage matters for the wider internet

Centralization delivers speed, scale, and security at a great price. It also concentrates risk. The November 18 incident was a clear reminder. Redundancy planning is not just for hyperscalers anymore. Even small teams can add guardrails like multi CDN patterns for static assets, origin shields, stale while revalidate caching, and clear maintenance windows. Small moves reduce big headaches.
