The China zone gets about 100,000 NTP requests per second (or maybe more, but that order of magnitude). It’s basically impossible to join it without getting tens of thousands of queries per second. To “bootstrap” it I’d like to add 25-30 servers (or more) at once (from anywhere in the world). I’m …

If your still looking for help in China and other underserved areas feel free to add in; IPv4 Address:5.9.71.156 IPv6 Address:2a01:4f8:161:81a5::2

I added 3 more servers to CN/IN zone. I am serving about ~20kqps at 1000 MiBit setting. Hope that took some load off of your servers.
