Highlights
- A major Cloudflare outage on 5 Dec 2025 disrupted key apps and websites worldwide.
- Indian trading platforms like Zerodha, Groww, and Angel One went down during market hours.
- Popular services, including Canva, QuillBot, and even Downdetector, faced access issues.
- Outage followed another massive Cloudflare incident in November 2025, raising reliability concerns.
- The event highlighted global dependence on a single internet infrastructure provider.
On December 5, 2025a large portion of the internet once again reminded everyone just how dependent it is on a handful of infrastructure providers. Cloudflare, the web performance and security company that quietly sits between users and millions of websites, suffered a fresh global Cloudflare outage – just weeks after its major November 18 incident.
Trading Platforms in India Hit at the Worst Possible Time
For Indian investors, the timing could not have been worse. According to Bussiness, popular trading platforms such as Zerodha, Angel One, and Groww were among the services disrupted.
During active market hours, even a few minutes of Cloudflare downtime 2025 can translate into missed trades, slippage, or unintended positions. Social media quickly filled with screenshots of error pages and angry posts from traders who couldn’t square off open positions or execute intraday strategies in time. While most platforms restored core functionality as Cloudflare deployed fixes, many brokers kept monitoring for “residual issues,” wary of glitches resurfacing mid-session.
A “Huge Chunk of the Internet” Suddenly Offline
It wasn’t limited to trading apps either. Globally, a variety of consumer and productivity tools were affected by the Cloudflare outage. Numerous sources reported that when Cloudflare’s network failed, services like Canva, QuillBot, and even the outage tracker Downdetector itself were impacted.
The irony was hard to miss: people went to Downdetector to check what was down, only to find that the site was struggling too. In the UK and other regions, coverage described the event as making it feel like “a huge chunk of the internet” had briefly vanished, with everything from creative tools to communication services throwing errors at once.
A Repeat Performance After the November Meltdown
What made this Cloudflare outage especially worrying is that it came so soon after Cloudflare’s November 18, 2025, meltdown, which had already taken down major platforms such as X (Twitter), ChatGPT, Spotify, Canva, and more for hours.
In its post-mortem for the November event, Cloudflare traced the problem to a buggy interaction in its Bot Management systems and to a database configuration change that cascaded across its global network. While the full technical root cause of the December 5 Cloudflare outage has not yet been detailed publicly, the pattern is clear: when one layer at a company like Cloudflare misbehaves, the blast radius can be planet-sized.
Why does One Company Going Down Break So Much
Cloudflare sits in a crucial “middle layer” of the internet – handling tasks like DNS resolution, caching, traffic routing, and security filtering for millions of websites and apps.
Because so many services front their traffic through Cloudflare, any widespread failure there doesn’t just affect a handful of sites – it affects banks, trading apps, news outlets, SaaS tools, AI platforms, and hobby blogs all at once. To ordinary users, it feels like “the whole internet is broken,” even though the underlying origin servers might be perfectly healthy.
Another reminder that the internet is a patchwork of dependencies, with firms like Cloudflare serving as keystone pillars, is the December 5 outage. Everyone is affected when one of those pillars trembles, from London-based designers working on a Canva project to day dealers in Mumbai.
Ultimately, this outage should push the entire ecosystem toward more resilient and distributed internet infrastructure.
