A brief global outage at Cloudflare on Friday (December 5) disrupted access to several Indian trading platforms, including Zerodha, Groww and Upstox, before services were restored. The incident affected user logins, order placement and market data feeds during active trading hours.

The disruption began around 2:26 pm IST, when Cloudflare’s network issues triggered failures across APIs and backend systems that many brokers use for routing traffic.

Upstox and Groww issued similar alerts, acknowledging an industry-wide impact.

Multiple brokers attributed the interruption entirely to Cloudflare, noting that the issue was not localised to their systems.
