Hello. Im back, I was very active about 5 years ago trying to get enough servers for the CN pool. An for a few years it was working. I still have 8 ntp servers in pool and alot better hardware than before. But during peak hours, that isnt enough. Most likely, the demand is also higher in 2024. …

Sounds good. Pressing both thumbs that it will work in the future. Long storry - short: I’ve asked a big company which is already present in the pool for some help and they saied: yes, sure :slight_smile:

[image] PoolMUC: I think it’s easy, just add a batch of CNAME RR from all countries or region subdomains to the global zone. According to the DNS standard, all clients will use global zone when they try to use region zone. This sounds like a good idea actually!

[image] Coelacanthus: just add a batch of CNAME RR from all countries or region subdomains to the global zone If it were a static zone, that would be true. But the zones are dynamically generated by the pool infrastructure as servers come and go, or are reconfigured. So that code would need t…

[image] PoolMUC: 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 c…

[image] Coelacanthus: I think it’s a good beginning to allow server owner modify the zones of their servers in Management Panel Sure, I’d welcome such a change, too. But given the bottleneck in getting things implemented, if it is a question of what to get done first if not everything can be …

[image] Coelacanthus: And @ask has some plans on it. Yes, those are what I keep referring to as technical solution, and there are different aspects being discussed in various other threads over time since then, but it is unclear to me as to where we stand with those plans as of today.

When the pool provides <region code>.pool.ntp.org domains, users naturally intend to use one that matches their regions. Only those with some insights on how NTP and the NTP pool works may think differ. So for majority of users that having “configuring a NTP server” in their minds, using their regio…

[image] HAHAHAHA: need to promote the use of global pool Another thing coming to mind in this context: For now, it should also be promoted to use the zones prefixed with “2.”, as only those have IPv6 servers in them. Those are often underutilized as compared to the IPv4 servers, so using the …

In fact, I don’t know whether it’s necessary to have 0/1/2/3 in front of the global pool. Why not just pool.ntp.org and have both Ipv6 and Ipv4 enabled for it?

If regional pools are eliminated, user cannot use them so pool.ntp.org will be the default.
