Also, some other technical and non-technical questions need to be considered first. E.g., as mentioned, other zones have smaller servers operating without issue because of a “good” client to server ratio in those zones. It needs to be managed carefully not to overload them, as could likely happen if the load of some larger zones is suddenly hitting the wider population with the flip of a switch. A more gradual approach is needed, e.g., by more and more people over time switching to the global zone. Or the infrastructure having a mechanism to slowly ramp up the share of traffic distributed outside the originating zone over time.

And @ask has some plans on it.

Fill zero-server pools with CNAME

The DNS system makes logs (and metrics) for how many DNS queries it gets from each country. Obviously that doesn’t quite correspond to NTP queries, but it should be a good proxy. My plan is to calculate for each country with less than X servers (or X “net speed capacity”) how far off it is the median/average/some reasonable comparison country and then supplement with servers either from the global zone or that have explicitly joined some other “extra global” zone. (If we use the global zone I’l…
