A major feature this morning is that for some search terms I can't turn off location (so today I get results for Bradford UK, which isn't even my ISP's location, let alone remotely near me). The only option I have is to tell Google where I am (I'm currently staying with someone called Winston Smith, who for some reason is very anxious I don't tell them).
Toggling between Web and Pages from the UK has no effect whatsoever.
The results for my main key term on that basis are nothing like anything I have seen before.
This unwielding preoccupation with location has been intermittent, but I have noticed it alongside a couple of major rollouts in the past, so we may be looking at Skunk after all.
