I don't know. It only works at the moment because I set up the hosting so that the default site is tehforum.co.uk. I have no idea how this change will affect that side of things so you can try it and see if it works.
Well it's working for me today, as it is others it seems. Pretty damn swift change over, I pinged www.tehforum.co.uk and it does indeed point to the new IPs.
