I do believe it's doing exactly what it's supposed to do.

g### asks for sitemap of olddomain.com

Request for olddomain.com/sitemap.xml is redirected to newdomain.com/sitemap.xml

g### accepts sitemap and files it under olddomain.com, since that's what they originally asked for.

I am feeling dizzy.

Are you shutting down the old domain? There's a place somewhere in gwt where you can tell them you're moving.
