"At the time of writing the site uses 21 virtual machines (VMs) hosted at different providers. [...] All virtual machines are hosted with commercial cloud hosting providers, who have no clue that The Pirate Bay is among their customers."

They may "have no clue" but it seems like that's only because they don't care and haven't looked. I don't see anything in the article that would prevent the providers from figuring this out unless I'm missing something.

Apart from the external-facing proxy (which is the most exposed link in this setup), these VMs don't need any sort of public presence. Unless the provider inspects processes running on all their customers machines, all they can see is a VM with opaque VPN connections to a few external ips.

I think only the load balancer would be vulnerable to discovery. Everything behind the load balancer could be a secure connection to a completely different datacenter if needed.

If someone is paying the bill, do they really care?
