If I go to my personal computer or my personal phone ( not on VPN connected to 
BLS network or using BLS resources) I can get to the site www.ssa.gov which I 
would mean to believe that it is able to resolve www.ssa.gov.

Does that mean the dns resolution for www.ssa.gov is not broken globally as 
explained below?

 Or maybe personal computer & my personal phone are querying different DNS 
servers over the internet which are able to resolve www.ssa.gov correctly and 
get to the website?

Thanks
Sandeep
