I see the same behaviour as OP when tracerouting dpreview.com - i.e. it blocks after ge1-3-biur147.servecentric.com
Presumably traffic from our IP addresses are being filtered.
Solution is either to use a proxy or to contact the server administrator and convince them to unblock your specific IP address.
