Google lists redirect as authoritative source

[FireDraken]

A site I'm working on has had number one ranking for a search of the brand name and still does, however the URL in the search result is sisterdomain.com:443 which is set up as a 301 redirect from another sister site with some common content.

For example the domain is brandname.com and the sisterdomain is brandnameasia.com and for some reason google has not spidered the site since Oct 13 (Now November 23) and nothing we have done seems to make any difference.

We have reloaded and verified the site maps using webmaster tools

Content on the site changes multiple times daily particularly on the home page.

Hope someone can help.

Here's the first steps I'd take:

1. Check your robot.txt -- eyes on, not just trusting what the GWT tells you
2. Check server logs to see whether googlebot is crawling and if so, what reponse code it is getting.
