The TENET router in London (196.32.209.25) connects to the Yahoo! AS, and the 195.66.224.0/19 router address is a giveaway that it's through LINX.

Testing other networks [target www.facebook.com] yields more data:

where hop 10's hostname confirms the LINX connection, and also shows we're still connecting to the Virginia servers.

The LINX looking glass also shows the routing to TENET through AS1299 (Telia) and AS2914 (NTT) and directly.

Traffic graphs confirm significant traffic through LINX


Several other autonomous systems are reachable via LINX peering sessions, including hosting providers Hurricane Electric and LeaseWeb and CDN Limelight Networks [ex YouTube providers, and 2009 Presidential inauguration streamers].

Clearly this is in preparation for the new SEACOM pipe, although TENET is saving on transit requirements.
