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 …

It is very difficult to maintain a presence right now or get into the pool. My own server was kicked out because it began to drop packets when it reached 80Mbps+ it and it is “fighting” to get back now. Even though it it kicked out, it still processes ~40Mbps of NTP traffic :slight_smile:

I’m just spinning up an 8-node anycast/ECMP cluster within our Manchester, UK, network. That should be able to cope with many hundred Mbit/sec. I don’t know how long it’s going to take for its stats to come into the CN pool: https://www.ntppool.org/scores/46.227.200.24

@hedberg out of interest, did it start dropping packets at 80Mbit/sec because ntpd was running at 100% of one core (because good old ntpd is a single-threaded process)? Or do you think it was because you had a saturated link?

@faelix I am impressed with the setup you are throwing at this :slight_smile: 5.103.139.163 is a LeoNTP server. It is a saturated link or at least so I think.

@hedberg ok, not a CPU problem then — we’ve got a LeoNTP as well, and as @LeoBodnar claims, it’s solid up to line-rate of ~110kqps. But it looks like there’s a lot more than that in the .cn zone. I hope this anycast cluster can soak up a bunch of traffic so that other nodes will recover. We can bri…

Four node and eight node ECMP clusters. Traffic has subsided a little (maybe China is going to bed?). Only around 80-100Mbit/sec of traffic on both clusters now (previously was about 100+100Mbit/sec). [41] Hope this helps alleviate some pressure on the rest of the .cn volunteer timelords …

I think the biggest problem of China region is the network to China from LA Monitoring Station(not GFW certainly). As a populous country, The international network of China are always congested, and ISPs needs to increase Qos level to guarantee everyone can access the international network, which ca…

Glad it helped - I guessed something had improved because we’re currently seeing less traffic than yesterday, and it’s great to see the zone is back up to 9 this morning :slight_smile:

Our anycast/ECMP node in the UK just hit the .cn pool. Almost instantly: 100Mbit/sec of traffic.
