Fair point. I'd meant to add "inside the US". The warrant hypo strongly implies this, though as you note, needn't necessarily.

Though outside the US, the NSA doesn't require a FISA warrant to intercept data, nor does it face any US legal restrictions on doing so.

The internet is as much of a monopoly outside of the US for example Tiscali in Europe. We have the same kangaroo courts when it comes to getting warrants to invade people privacy.

At least from a general perspective I don't see a big difference.

But it's not one or the other; an EU court will make a warrant for the ISP traffic data, and an US court for the DNS requests. You become vulnerable to both.

1.1.1.1 operates on edges of CloudFlare CDN - EU users will be handled by EU DNS server. And there’s no logging.

Cloudflare is still a US company. Do you have any FISA jurisprudence showing that simply running the server on another country makes it immune to warrants?

> And there’s no logging.

Until the courts say there must be.
