Cloudflare Outage 2: How One Company Can Have Global Impact

On December 5, the American Internet service company Cloudflare reported a system failure, causing millions of websites to stop working globally, including some service websites familiar to Internet users such as Canva and QuillBot.

According to techgenyz, this is the second time in less than a month that Cloudflare, the web performance and security company that silently connects network users and millions of websites, has encountered this serious problem.

This once again reminds everyone of the dependence on a few infrastructure providers.

Trading platforms in India were the worst affected in this incident. According to Moneycontrol, popular trading platforms such as Zerodha, Angel One and Groww were among the services disrupted.

The outage occurred at a time when trading was at its busiest. And even a few minutes of Cloudflare downtime could lead to missed trades, slippage, or other unintended risks.

Social media quickly became flooded with screenshots of error pages and angry posts from traders unable to process orders. And even as most platforms restored core functionality as Cloudflare rolled out fixes, many brokers continued to anxiously monitor “remaining issues,” wary of recurring glitches mid-session.

“A large part of the internet” suddenly stopped working

The problem wasn't limited to transactional apps. Globally, many consumer tools were affected by the Cloudflare outage. Multiple sources said that when Cloudflare's network went down, services like Canva, QuillBot, and even the downtime monitoring tool Downdetector were affected.

Ironically, people turned to Downdetector to check for problems, but it turned out the site was down too. In the UK and elsewhere, news articles described the outage as a "huge chunk of the internet" briefly going down, with everything from creative tools to media services crashing at the same time.

Performance repeats after November crash

What makes this Cloudflare outage particularly worrying is that it comes on the heels of Cloudflare’s November 18, 2025 outage, which caused major platforms like X (Twitter), ChatGPT, Spotify, Canva… to go down for hours.

In its November incident report, Cloudflare traced the issue to a communication error in its Bot Management system and a database configuration change that propagated across its global network.

While the full technical cause of the December 5 Cloudflare outage has yet to be released, the pattern is clear: when one layer at a company like Cloudflare goes awry, the impact can be planet-wide.

Why does one company failure cause so much damage?

Cloudflare sits at the crucial “middle layer” of the internet—handling tasks like DNS resolution, caching, traffic routing, and security filtering for millions of websites and applications.

Because so many services route traffic through Cloudflare, the outages wouldn't just affect a handful of sites — they'd impact banks, trading apps, news sites, SaaS tools, AI platforms, and hobby blogs all at once.

To the average user, it feels like "the entire Internet is down," even though the underlying root servers may be working perfectly fine.

The incident also serves as another reminder that the internet is a tangle of dependencies, with companies like Cloudflare serving as its main pillars. And when one of those pillars falters, everyone is affected, from designers in London working on a Canva project to daycare agencies in Mumbai.

Ultimately, this outage will push the entire ecosystem toward a more resilient and distributed internet infrastructure./.
