Does Fly.io publish any kind of IP-range-to-region mapping ?

I would also really appreciate some listing of the current outbound IPs for a given region.

We are working through an issue right now where requests to Google Cloud’s APIs (ie all requests to googleapis.com) are being blocked with 403 errors, but seemingly only for outbound requests from our Singapore-region fly instances.

We have a high priority support ticket and are working with the Google Cloud team to try to resolve the issue, but it is hard to resolve given I cannot give them helpful diagnostic information about what IP ranges these blocked outbound requests are even coming from.

Would really appreciate this, even if just a short-term one-off listing for the time being, to help us diagnose the issue with Google Cloud blocking our outbound requests from Fly SIN instances.

Thanks,
Ethan
