Yes, I'm certainly aware of the other partitions. That's why I said all the
public cloud regions outside China.
Yeah, "govcloud" is technically available to the public, although there are other partitions reserved for government use that are not, and the naming is a big hairy mess. Many service teams don't have any US-citizens-in-the-USA working for them, and they cannot in any way adequately support these regions.
My on-call experience improved significantly when I moved from the US to Canada, and I got taken off the (extremely thin!) list of engineers eligible to ssh into RDS instances in Govcloud. There were so few USA-citizen-in-USA engineers that I had been getting tickets for services and instances in Govcloud about which I had only the very thinnest knowledge… and then I was limited in my ability to consult with others who were actually experts. The customers in Govcloud paid a premium to be there, I got paged for a bunch of tickets which I was ill-prepared to handle, and it was generally a bad experience for everyone.
Working with the airgapped secret/top-secret partitions was even worse. You would get paged incessantly and then someone who was cleared for access but knew almost nothing about the service in question would have to go to a SCIF in the DC area, and you would exchange screenshots and text instructions with a turnaround time of hours or days.
