Hi Barry, Thanks for the suggestion. Plugged in the URL to REDbot and got the following results. It doesn't look like it's a caching issue.
HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Disposition: attachment; filename="lbls.kmz" Content-Type: application/vnd.google-earth.kmz Transfer-Encoding: chunked Date: Mon, 21 Jan 2013 20:42:39 GMT General - The server's clock is correct. Caching - This response allows all caches to store it. - This response allows a cache to assign its own freshness lifetime.
