I am just and end user. So I dont know where to put this. please transfer this to a relevant forums, if needed.

 

For the last month, If I use any public DNSes like Google DNS, Open DNS or even nslookup using n0g.akamaiedge.net  I cant open certain websites like support.microsoft.com themeforest.net (and all its affiliates like codecanyon.net etc) . There is no issue if i use my local ISP DNS. The issue for first logged to Google DNS documented here. They said this seems to be an issue with Akamai. I am rewriting the troubleshooting nslookups command here also.

 

The problem occurs on my local ISP (Airtel Broadband). For the last week some websites(but never support.microsoft.com) did open but just for an hour or so.

The problematic IP  is 23.35.x.x . I have done fresh lookups below:
