Thanks Frank - www.linkedin.com is the one i see problems with testing from two locations UK and Frankfurt. London TR is below. If i jump out of our AMS location (ASN109 - via AS1299 ) i dont see any problems.

Stuart,
You don't tell us if it's www.linkedin.com or linkedin.com, but in any case, because they serve up that site around the world using some form of GLB it may resolve to different IP depending on where you are. From my perspective it is working via Cogent, and I can hit 108.174.2.129, too:

No reply from LinkedIn support, but i see plenty of Verizon and Level3 customers cannot access LinkedIn for 24 hrs. 216.52.242.113 works ok.
