And on the hidden website there was a link back to cia.gov somewhere.

On the other hand I'm surprised tor works in China at all. I would expect the Great Firewall to shut down all entrance/exit nodes going into or out of the country, except maybe for a few controlled by the government.

The security level varies frequently. It's known that meek still works in China, which is probably a major reason why both Google and Amazon have shut down domain fronting.

Which sounds like a management decision to cut costs by running them on the same server. This is probably why we are seeing ex regime department heads in the news lately as political pundits in hopes they create enough deflection to avoid prosecution for 30+ agents dying on their watch.

Do you seriously think the CIA cared about server costs for something like this?

The less money they spend on this kind of thing, the more they have to funnel to their second cousin's shell corporation. With no oversight, performance degrades.

Sure, that's some manager's performance bonus. When I briefly worked for Nav Canada our manager decided to buy the cheapest dollar store pens possible in order to pad his performance metrics. We also had to sign them out individually from his safe. Not at all surprised if a CIA manager did a risk analysis and decided lets use the same server(s) and save a few dollars the risk is acceptable.
