Re: Google is not turning up any new peering on IXs?

[Tom Beecher via NANOG <nanog () lists nanog org>]

- Google never segmented Google proper traffic from GCP traffic in their
public peering connectivity.
- GCP traffic creates different traffic patterns that cause congestion
problems to IXes where they haven't expanded capacity enough.
- GCP networking tiers are such that they need to have a shitton of
capacity to transit providers.
- It's cheaper for them to do large, centralized capacity to fewer external
networks than it is to try and constantly manage capacity at all these
individual IXes.
- GCP is Google's fastest growing revenue stream, so everything GCP is more
prioritized.
