why cant I get to www.freeparking.co.uk

[#1]

I have a number of domains names hosted at freeparking, but freeparking.co.uk and their homebase of freeparking.com are both unresponsive.  Is this a plusnet issue or is it just that freeparking have gone awol ?

[#2]

I can get to both, but both are very very slow.
Can you post a traceroute to it?
Start > Run > 'cmd'
At the prompt type :-
tracert www.freeparking.co.uk
Does it get stuck anywhere?

hey liam,
when I posted there were completely non-responsive, but i am getting some intermittent access now, but slower  than a slow modem. 
Trace route to freeparking.co.uk runs 18 hops and then subsequent hops just time out. 10 of those hops are within the cogentco.com so maybe its gettin in a loop somewherer there.
As all my domains are DNS-ed by freeparking, its making them almost inaccessible too.

I'm able to access the site fine, but it doesn't appear to be responding too pings.
