I think we both agree there is no perfect publication of where their =
servers actually are
Given Ahmed is asking "Does anyone know if AWS amazon =E2=80=9Ccloudfront=E2=
=80=9D, cloud flare, Microsoft =E2=80=A6 etc, hosting their servers on =
other party providers?=E2=80=9D
i think the answer you given which is=20
>>>=20
>>> In general, only the big three (Akamai, Netflix, Google) have =
significant deployments inside eyeball networks. Exceptions to every =
rule and all that, but if you pick random large eyeball network, chances =
are very, very high they have no one other than those three - if they =
have any at all.
good one
