I can only see the problem using Google.com Advanced and also on one AdSense page. I tried adding &gl=uk/za etc but no go.
Hope this is just a temporary and new glitch. :(
It only happens when I use google.com, not google.com.au. Previously, google.com would give me AU-targetted ads.
I can break out by adding &gl=us but this won't help me with other PPC providers.
My view is *somewhere* in the US, not the Bay Area (where I have a proxy and can call up regional ads to confirm it).
Question: How can I tell "where" in the US my Google view is? What terms can I try to bring up a regional ad easily? I have tried "homes for sale", "dentist", "apartments" but can't raise a single regional ad.

I'm not an expert by any means about IPs and identifying regions, however just because G thinks your in the US - doesn't necessarily mean they know where in the US you are.
Case in point. I have a cable modem. If I'm connected via the modem (i.e. no router) G usually knows where I am. If I'm connected via wireless through a router, I rarely get served regional ads - its like they can't tell where I am suddenly.
