In chrome, when trying to access http://hirewhen.com

    This site can’t be reached
    
    hirewhen.com’s server DNS address could not be found.

Same story when trying to resolve the domain in the console

    $ host hirewhen.com
    ;; connection timed out; no servers could be reached

EDIT: Looks like it's an issue when coupled with Google's public DNS servers

    $ host hirewhen.com 8.8.8.8
    Using domain server:
    Name: 8.8.8.8
    Address: 8.8.8.8#53
    Aliases:
    Host hirewhen.com not found: 2(SERVFAIL)

ISP DNS servers work fine.
