Fintech apps Zerodha, Groww and Angel One were down on Friday afternoon after an outage hit Cloudflare for the second time in a month. The websites showed "500 Internal Server Error" as users tried logging in. The Cloudflare outage also affected downdetector.in, the website that tracks downed websites. Cloudflare said at 2:42 pm (IST) that it had implemented a fix.
