The difference with vilefoxdemonofdoom's trace is from the different kind of packet (ICMP vs UDP) used for the traceroute (UDP packets don't reach the same IP address as ICMP or TCP packets):

I didn't have any trouble opening http://www.purrsinourhearts.co.uk/

Thanks for clearing that up. However, as HTTP packets go through the .61 machine to get to .62, if the website is available the .61 machine must be also, so we're down to problems on that machine if its HTTP server can't be reached.
