Depends which looking glass you obtained the show bgp output from - it should be noted that any Looking Glass can only provide its' own view of the Internet, not that of another AS or even router within its' own AS.

Looks like Virgin are using the cheapest route to the website by the way, which is via their peering at DecIX in Frankfurt, rather than using paid for transit which may be more direct.

It should be noted that this is not in any way uncommon, ISPs as a general rule try and avoid transit costs where possible, that's the point of peering.
