Be careful joining an IX just to peer with Google (AS15169) and a few =
others...especially if your exchange doesn=E2=80=99t have route servers =

Some companies, such as NetFlix, have a truly open peering policy; =
establishing a bilateral BGP session with them is super-straightforward.
On the other hand, Google=E2=80=99s actively-enforced policy requires =
you already exchange 100Mbps+ w/ their netblocks: upon requesting a =
session they=E2=80=99ll monitor/check related traffic for a few weeks =
before following up on your initial request.

As for transit across IX fabric, I know that HE.net is at least willing =
to discuss such a possibility (just started this exact discussion with =
their NOC last night), although they discourage it for reasons pointed =
out by others in this thread. On the other hand, with a willing transit =
provider, if you prepend your AS a few times=E2=80=A6an IX's fabric =
makes a very cost-effective failover.
