URL redirects to Appspot.com and I want to remove it

[Brad Bowers]

A previous engineer that is no longer with us had setup a status page for an application on appspot.com.  For example "test.domain.com" when down would redirect to this status page.  I want to remove this redirect to send this to a new status page, but can't figure out how the redirect was performed.   Currently I have deleted the old DNS entry both internally and externally to test.domain.com.   I have configured a CNAME for test.domain.com to point to status.domain.com.  Status.domain.com is a local server internally where we just have an IIS page displayed for the outage.  So this works fine internally when trying to access https://test.domain.com it redirects to https://status.domain.com.  Externally it works for both http and https.  However, internally when accessing http://test.domain.com I am getting redirected to status.appspot.com.  There are no other internal DNS entries for test.domain.com and I have cleared DNS cache and flushed cache internally.  How is this being redirected to the appspot status page?

Hey Brad,

Google Groups isn't really the right place to look for 1-on-1 support, although I'm happy to provide some advice on things you can test for. Generally, a question like this should either be answered through opening a support ticket, or through posting to stackoverflow with enough information that somebody could begin to understand the problem.

In order to determine whether you're dealing with a 3xx redirect or a DNS redirect (CNAME record), you should run some commands which test the HTTP responses from test.domain.com are in the 300-399 range, or whether there's a CNAME record on that domain.

You can run the following command to check the HTTP response status and headers for test.domain.com:

curl -s -D - http://test.domain.com -o /dev/null

You can run the following command to check the zone file of the domain:

dig test.domain.com

 I'll monitor this thread to see if you have any trouble with this, but keep in mind that in-depth 1-on-1 support isn't meant to be provided via this forum. Wishing you luck!
