Hi all, Speaking of Virgin media, observed something odd the other day, wonder
if anyone can spread any light on it, a BGP network with its own AS and PI
space has a connection to Virgin Media which they pay for, and use as a backup.
They have a bigger connection to a Tier-2 also paid for transit, used for most
of their traffic. They observed that a large amount of youtube and netflix
traffic was going to VM, which was not desirable I checked the routing and
actually Netflix and Google was preferred via the bigger connection not VM.
The reason the traffic was coming in from VM is, that when people are using his
PI IP's and connect to youtube or netflix, it seems 70% of the time, the media
IP (when the content starts) is from VM PA space, not Netflix or google IP's. I
might expect this if I requested the content from VM PA space, but not on PI,
and how did netflix and google learn that his PI space has a direct route to
VM, obviously you could pick it up from the BGP tables, but are they really
looking?
Massive coincidence or is their some intelligence going on here?
