Sorry about the recent downtime, my host appears to have had some major problems, and when they finally did bring the server back online it had a new IP address, so I had to update my name servers, blah blah blah.
And to make matters worst for me, this all happened last week whilst I was away at Microsoft’s UK Techdays event in London. Anyway, my host’s server problem now seem to be stabilising, so hopefully no more downtime (but don’t hold your breath)
