Most peered AS per country

Hello Baldur,
    if I'm not wrong, CAIDA are using Route Views and RIPE NCC RIS as 
data sources. If your AS (or any ASes in your customer cone) is not 
feeding any BGP route collector, your peers will never appear in their 
rank. Some of your peers may be seen if any of your peers are connected 
to a route collector though. Data available is extremely incomplete from 
that point of view... If you wish to have more reliable data from BGP 
analyzers using public data, I suggest you to join a collector. I run 
one of them (Isolario), if you need any more details about that (or 
about the data incompleteness) just drop me a mail!

Best regards,
Alessandro Improta
