A publishable range of external IP addresses for Buildkite that isn’t all of Amazon. Eg Zendesk, Travis, Github etc.
Why
Many organisations run egress firewalls that require whitelisting of CIDRs for external communications for security reasons. By having a publishable range of external IPs you make Buildkite palatable to the security engineers in those organisations.
Good call on this one. This is something we’ve been discussing internally for aaages. Amazon hasn’t really given us any good tools to address this, but I think that’s about to change.

I’ll do some poking internally and see where we’re up to with it.
