Welcome back @Gautamkhurana!
Your site open just fine for me. It could be a Jio or Airtel’s temporary problem resolving to certain IP’s (which may have iFastNet’s, idk). As for me, it is opening on Airtel.
Seeing how your website is working fine from one ISP, it’s 100.000% not a server problem. A server can be fast or slow, but can’t differentiate between where the connecting is coming from.
The issue must be somewhere in the network between Airtel and our servers. It could be a routing problem somewhere, or maybe an intermediary networking partner having issues.
Could you please make a traceroute from your device to our servers using both Airtel and Jio? That way, we can compare the differences.
Just search the web? There tens of thousands or articles online on how to make a traceroute.
Be sure to specifically search for the platform you’re using. Making a traceroute on Windows or MacOS is very different, and I have no idea how you would do it on a mobile platform like Android or iOS.
GUYS UPDATE- Now site is working fine. I think there was a problem with airtel. But thanks to all… who tried to help me. Moreover, you guys including admin are better than ifast net support. Thank you for your help.
