Greetings. We have two internal DNS Forward Lookup Zones (Windows Server 2008 R2):
We rarely use the second domain (blahblah-B.org), but we have a an Alias (CNAME) record in it to redirect internal connections to our website from our rarely used domain to our main domain name. I.E.
www ---- > Alias (CNAME) ---- > www.blahblah-A.org
Alias is: www
FQDN is: www.blahblah-B.org
FQDN target is: www.blahblah-A.org
Our DNS is Google DNS. Our DNS record for the rarely used domain, blahblah-B.org, is set up to forward to our main website - www.blahblah-A.org
Our website is hosted on Pantheon.
From OUTSIDE the organization, I can enter: www.blahblah-B.org
in any browser and it redirects correctly to: www.blahblah-A.org
FROM INSIDE our organization, when we enter www.blahblah-B.org
into any browser, we get a 404 - Unknown Site error from Pantheon
Does this sound like a Pantheon configuration issue ? A DNS forwarding issue ? Some sort of DNS security or relay issue ? I'm lost.
