You can add as many regions as you would like to a single service, at least as long as it doesn't have a volume.

Ok. What about the private networking?

Currently, all my services (public and railway.internal) are running in Amsterdam.
If I give the public service a US region, do I need to do the same for the other services?

I have 1 volume, its private and in Amsterdam.

Private networking works across regions too.

But please know that the private network is not region aware..

Say you have your public service deployed into our 4 regions, and you also have a private service deployed into our 4 regions, whenever an instance of your public service makes a request to the private service, there is a random chance it makes a request to any region, not just the closest region.

hm i see ok

ok so best practice is to cover all the regions with all the services (regardless of access) and they'll ping the closest one 99% of the time

except volumes?

They will not connect to the closest one anywhere near 99% of the time, the private network is not region aware.

I see, alright.
So, I can create multiple regions for the public service and they'll way to the private services via private networking

If you set it up like that, yes.
