Hello Everyone,

I have a question to the bdNOG community. I believe someone knows the answer.

Question is "How does Google select their Cache Engine IP nearest to the request sender?"

No doubt, they look at BGP tables for ASN of request sender but I want to know more specifics like,
do they look at BGP attributes, if yes then what BGP attributes, any algorithm other than BGP etc.
Thanks in advance.
