Why is access to Kite app restricted by the internet provider?

Zerodha uses Cloudflare as the content delivery network (CDN). If your internet service provider's DNS server does not support domains under Cloudflare, your access to Zerodha services like Kite, Coin, and Console could be affected. To resolve this, change the DNS server to Google's (WEB) DNS on the computer or phone or use an alternate connection.
