I am not using Binance or any other exchange but whenever I tried after they announced the ban I can access the URL with no issues at all and that too from Jio and Airtel mobile network connections.
ISP not yet blocks the URLs all over the country if I am not wrong but sooner or later it will stop working.
After the news was out of the URL ban I did try accessing binance but failed using my Airtel mobile connection. It did give me a blank page and from that time I have been using the Binance.me URL to log in to my account. Yesterday I saw a couple of posts on Reddit where users were again able to access binance using the .com URL and therefore I checked and it was working for me. Not sure why Jio allowed the access they are known to follow government directives instantly. Whatever the case was or is I am happy that it is working for me now.
