FYI Hathway is ISP in India.
I observed that the website changes were not reflecting in my browser So I tried to open same website from the JIO network and it worked!
What I observed is that Hathway has it's own DNS server. I am guessing that they must be storing web cache along with their servers to reduce network traffic which may be the root cause of this issue.
You can compare the below screenshots for the same.
