Cloudflare down: Users unable to use multiple app, Groww and Zerodha also hit in India

Cloudflare engineers reported an “internal service degradation” on Friday, December 5, 2025. The ensuing outage affected a large number of users globally, cutting off their access to many popular apps and websites.

In one of the tweets by a user from India(BHARAT), it was written:

“Cloudflare is down, so apps like Groww, Zerodha, where I use to invest in the stock market, cannot be accessed. While in India(BHARAT), this is just during trading hours and it is overcast, I can’t access it and Downdetector is also down, so don’t know if others are having the same problem. It is going to be funny.”

Cloudflare has taken note of the outage, and worked quickly to bring its services back online.

Which sites are impacted by the Cloudflare outage?

According to reports, several sites have faced or are still facing disruptions due to the outage. They include:

• Zerodha
  
• Groww
  
• Canva
  
• Zoom

• LinkedIn

How bad was the Cloudflare Outage?

Cloudflare is used by many major sites to protect their networks against attacks as well as to improve site performance via Cloudflare’s content delivery network (CDN), DNS resolution and Domain Name Service (DNS) routing services.

On Friday, when Cloudflare experienced “internal service degradation”, multiple major apps, websites, and platforms that rely on Cloudflare were taken offline or experienced major service issues and disruptions.

The problems were widespread and global – affecting companies and users across the world.

While some reports provide links to a long list of impacted websites and platforms, these include some prominent digital properties and services in a wide range of categories, including:

• Finance and trading apps/sites (Groww, Zerodha)
  
• Productivity and design tools and apps, document/collaboration tools, professional services platforms
  
• Social and professional networking
• Media, content, e-commerce

Specific reports mentioned stocks websites and platforms, as well as payments-related services; there were multiple mentions of media and publishing (news, content sharing), with issues reported for several social media apps/platforms.

Cause of the Cloudflare Outage

Cloudflare “logged” the issue as an “internal service degradation”.

It is possible that multiple different issues were noted by other outage-tracker services; according to these and other social media reports, there were API failures associated with Cloudflare’s status dashboard.

Cloudflare Response to the Outage-

Cloudflare’s engineering teams located the issue and fixed it relatively quickly, on Friday. By the early afternoon (UTC), major services were restored.

On their status page, Cloudflare provided a statement, saying that they noticed a degradation of their services, and were monitoring the situation, and working to bring them back up.

Cloudflare Outage Impact and Reaction

As is the case with many major service outages, the reaction from the userbase was immediate and vocal, with the outage being talked about widely on social media.

The impact was especially negative for users trying to access particular services for their day jobs, particularly for retail investors in India(BHARAT) trying to trade on popular investment and trading apps like Groww and Zerodha.

Reports from India(BHARAT) mention that this outage hit at a very bad time, as many people were using the apps during trading hours; being unable to make trades, updates, or follow real-time developments was frustrating. Down detector being down at the same time didn’t help.

Users and visitors who encountered errors when trying to access services ranging from stocks and payments to content and social media shared their thoughts on Twitter, while others lamented and vented their frustration.

Cloudflare Outage Fallout

The outage and its impact were notable for its scale, as well as because Cloudflare is such a major back-end infrastructure provider for many major digital properties.

A relatively small number of companies power much of the online world, and any outage at the cloud-backend level can result in a sizeable number of websites, apps, and platforms being disrupted or going down entirely.

Cloudflare, too, has been down before: an earlier outage, on November 18, 2025, had also impacted a large number of users, and several major services; the company traced that issue to a configuration-error bug in the “Bot Management” product.

For some, the Friday outage also underlined a major concern with this high-dependence on shared platforms: even short-term outages (or scheduled maintenance windows) can lead to disruptions, inconveniences, lost opportunities, or chaos for end-users, in some cases.

As of this writing, services may have been restored; but many users will have plans in case of further Cloudflare outages in the future.
