Still not fixed for me in Hereford.
For a split second when opening Google Homepage I get page cannot be displayed then it opens.
Primary DNS 184.108.40.206
Secondary DNS 220.127.116.11
I've just had a further update to say that they are aware of an issue, I'll post back as soon as I hear anything further.
I tried again last night and had no joy, so there clearly is an issue that still needs to be resolved (I'm based in North Wales for anyone who is interested).
I would like to change the DNS to google but like others have said I think the Homehub restricts you from doing this (I am using HH3).
Really hope it gets sorted soon, got a lot of jobs I need to do online and I'm eating into my 3G allowance for the month!
Even if you change you client DNS entries, BT are intercepting these requests (Google or OpenDNS).
A VPN is one solution.
This is worth a read although I'm not sure how much is still relevant - http://linuxforums.org.uk/index.php?topic=11464.0
