> You can only point to IPs in China from DNS servers in China - if you try to use, say, Route53 in the US and add an A record there, you'll get a nasty email (fail to comply, and your ports get blocked again, possibly for good).
Wait what? So I can DoS any Web site in China by creating a rogue DNS record that points to its IP address, even under a completely unrelated domain? How would they even find those records?
I guess they would find it the moment someone in China using a Chinese resolver tries to resolve your rogue record, since that would recurse to one of the root mirrors in China, which presumably feeds this mechanism.
Seems like a very minor speed bump in your plan, though: presumably something like https://www.chinafirewalltest.com would achieve that, or send a few emails for folks to click.
