Currently I have two hosting companies in the US a fast VPS for my tracking and a shared host w/ hostgator for websites that I don't want people who see my tracking link to know about .
Should I host the .co.uk on a third host in the UK? I know in the past that mattered but I'm seeing some conflicting info from various google reps in google groups and Matt Cutts about the topic.
I'm wondering about the real world... for those of you that have websites in other countries have you seen penalties for hosting websites outside of them? Or are any of you doing this and still ranking well?
