unable to create postgres instance in jnb

fly pg create --region jnb is not able to provision new postgres servers. fly pg create --region ams works just fine. The status page doesn’t give any indication that anything is wrong.

I’m just going to carry on in Amsterdam for now, but would ideally like to host it all in Johannesburg.

The command outputs the following, then hangs for 30 mins before I close it. fly pg list shows the app as pending.

Creating postgres cluster in organization personal
Creating app...
Setting secrets on app bitter-butterfly-5383...
Provisioning 1 of 1 machines with image flyio/postgres:14.6

Any idea what the problem might be?
