Website not accessible through some ISP/Internet Connections

I have changed my Name servers to Netlify Name servers .
My website is not accessible via my Local ISP although it is accessible by some major ISP in my area.
What could be the reason for this and how to resolve this issue ?

Hi, @sicmundus, the reason is most commonly time to live values of the previous (not the current) DNS records:

If that isn’t the issue, would please let us know which domain name this is for?

If you can install dig for your local system, traced lookup of the record from a non-working ISP would be helpful:

dig +trace

​Please let us know if there are questions or if TTLs are not the root cause.

Hi Luke,
Thanks for your comment.
Actually I was just now able to resolve this issue by using Open DNS in my laptop ! :grinning:
