Did some setting get screwed up in your router or machine that is potentially using a London based proxy server?

I believe most of those are done via geographic IP location tables -- but, the IP showing on your posts here is similar to the one you usually post with and according to the maxmind database, is in NY. It does seem odd that all engines would make the wrong assumption which makes me wonder. Do other machines on your home network also do the same thing? If not, then it is localized to your machine and is more likely a proxy issue. If they do seem to search London sites, then it is more likely an IP issue.
