Weird problem on BSNL Fiber

Initial info :
DNS - NextDNS
Ip series - 117.xxx.xx.xxx (Bangalore server)

This morning , when I fired up laptop for a Google Meeting , google(whole of google) seems to be down whereas 8.8.8.8 and 1.1.1.1 is reachable
The weird thing is ping to websites like google.com is not reachable whereas DNS is pingable


I thought there might be some problem with the NextDNS server and changed it default BSNL`s DNS (National Internet Backbone)
Popular websites started loading
Amazon(AWS)
Google
Facebook servers
and some popular hosts
I am not able to connect a VPN and whole of the internet still

I just want to know whether the fault is at my side or BSNL`s side

Seems fine over here... 🤷‍♂️🤷‍♂️

Well I am back now . idk how ...maybe problem on BSNL side 😅

Bsnl always surprises us... If everything seems fine like signal and Rx and pon light and all..
The go to method is to restart the router.. Mostly you will get a different ip and it might be fine. This has worked at times not every single time.. When the network is really down due to some other issues
