Timeout accessing linkedin.com over BT Broadband connection

When I try to connect to linked in from home over a BT ADSL connection it times out. If I do a traceroute I can see it going to llnw.net and that is where it appears to timeout - are you using Limelight networks CDN ? Could they have a problem. If I connect from any other network it's OK. I can connect to any other website from my network. I do not have any firewall settings preventing surfing (hardware or software). I am using a Mac and have tried Safari and Firefox.
