Kite is disrupted by a Cloudflare outage, but Zerodha’s backup system saved the day
The internet was severely disrupted on December 5, 2025, due to a worldwide outage at Cloudflare, a significant provider of DNS, content delivery, and web security infrastructure. Zerodha’s Kite, India’s biggest retail broking platform, was one of thousands of websites, apps, and fintech platforms that went down.
What Specifically Occurred
As an intermediary layer, Cloudflare effectively and securely filters and routes web traffic. All services that relied on it were momentarily unavailable when a technical issue caused its systems to go offline. Several users were unable to access the Kite web and app, despite the fact that Zerodha’s internal trading systems continued to function. Orders were delayed, login errors occurred, live market data was missing, and the site was generally unavailable during market hours.
Depending on the location and ISP networks, the outage lasted between thirty and sixty minutes. Access to Kite gradually returned to normal after Cloudflare implemented a global fix.
Why Numerous Platforms Were Affected
It became clear that there was a structural problem: the Indian broking sector, like many other international financial services, depends on external cloud and CDN infrastructure for stability, security, and speed. Although the main trading engines continue to operate, platforms such as Kite are unable to interact with their users when this layer fails. Therefore, the outage was an access issue brought on by a third-party provider rather than “a trading system failure” within Zerodha.
Zerodha’s Reaction: The “Kite WhatsApp Backup”
Zerodha has developed an emergency backup system called Kite Backup, also known as Kite WhatsApp Backup, to keep traders safe during external outages. This lightweight interface does not use Cloudflare; instead, it operates on independent infrastructure.
Zerodha publicly declared that the main platform was momentarily unavailable during the Cloudflare outage and advised users to use the WhatsApp channel to cancel pending orders or square off open positions.
This backup system is only meant to be used in an emergency and is purposefully simple. It allows users to:
- View available positions and holdings
- Verify the fund availability and margin.
- Cancel orders that are pending.
- Leave (square off) current positions
Fresh order placement and sophisticated trading features like limit orders, option chains, GTT, basket trades, and analytics are not permitted. Risk protection during outages is the main objective, not convenience.
How the Backup System Operates
In order to utilise the WhatsApp backup, traders need to:
- Keep the number +91 99644 52020 handy.
- To start the authentication process, send “Hi” on WhatsApp.
- Enter your PAN and Zerodha user ID.
- Verify identity using SMS-OTP
- Select from the options to view positions, cancel orders, or leave.
This process is purposefully kept outside of Zerodha’s main infrastructure to prevent it from being blocked by widespread internet routing issues.
Why This Backup Matters
For intraday traders and those with leveraged derivative positions, even a few minutes of downtime can result in severe losses. The ability to exit or cancel positions during outages, even through a limited WhatsApp interface, affords:
Risk mitigation
Control during unpredictable failures
Reduced panic in the trading community
It was the first significant real-world test of this emergency channel, and it proved very useful.
Limitations That Users Need to Consider
Kite Backup is not a trading alternative. It:
Cannot place new orders
Does not support advanced order types
Does not show full analytics or charts
Might show limited positions during high traffic
It is designed for one purpose: last-resort exit protection.
Lessons Learned & What’s Changing
Following the outage, Zerodha founder and CEO Nithin Kamath made a public apology for the disruption caused and admitted the industry was increasingly reliant on global cloud and CDN providers such as Cloudflare. He also reiterated that the firm was committed to improving infrastructure resilience.
Going ahead, Zerodha intends to:
Reduce reliance on a single CDN provider
Diversify routing strategies
Explore Multi-Cloud and Multi-DNS Architectures
Add more layers of redundancy for mission-critical user access
What Traders Should Do Going Forward
To prepare for rare outages:
Save the Kite Backup WhatsApp number now +91 99644 52020
Use it only from your registered mobile number.
Keep login information and PAN at hand for speedy authentication
Maintain a backup internet source (hotspot/alternate ISP)
Follow brokers’ official status pages or social updates during disruptions
Final Thoughts
The 5 December Cloudflare outage had shown that trading platforms depend upon complex global infrastructure. Even if the internal systems of a broker work just fine, external failures can block user access at times. The proactive WhatsApp-based backup ensured a practical safety net for the traders at Zerodha, proving that resilience in this modern kind of financial technology is not just about speed.
