Are you using any proxy or VPN? Some websites block those. Also, what IP address does the hostname resolve to. I get 23.43.19.161

nslookup www.vistaprint.co.uk
Server: 10.1.1.1
Address: 10.1.1.1#53

Non-authoritative answer:
www.vistaprint.co.uk canonical name = www.vistaprint.at.edgekey.net.
www.vistaprint.at.edgekey.net canonical name = e14161.a.akamaiedge.net.
Name: e14161.a.akamaiedge.net
Address: 23.43.19.161

Is it possible it requires https, not http?

Getting access denied either way. Still works mobile

a bit confused by the mix of responses, some say its fine and others not, hmm...

It wasn't accessible earlier, but now it seems ok

It could be it was a case of the change they made propagating (at different times) round the various DNS servers used by the posters that had trouble.

Also the original recommendation to clear cache might have worked, as that would have the http.
