I was operating under the assumption that there was still a
strong desire to maintain maximum diversity between the nameservers,
and continue to have multiple different groups provide these
services. Assuming that's the case, then eliminating all but the
"best" nameserver in each group would make the most sense.
If you don't care to maintain that organizational diversity
between the various nameservers, then you can choose alternative
solutions.
The "refresh" and "retry" are both set to 900 seconds, which
kind of eliminates the value of having a retry at all.
True, but that is irrelevant for everyone except the people running
the name servers.
Yeah, but most of the operators of the existing nameservers are
on this list, so this is not a totally irrelevant subject.
The truncation isn't *too* bad since it is just the A records for the
name servers that are getting tossed. That will cause uneven load on
the various pool name servers, but not on the pool NTP servers
themselves.
Any time there's truncation, the resolvers have to retry with
TCP. Given broken firewalls and all the other known problems, this
causes very serious issues with the nameservers for the project.
This also causes problems for many NTP clients that use pool.ntp.org,
because they can't get good (or any) DNS resolution within this
domain. The very low TTLs cause this problem to be compounded many
times over.
By the way, thanks for noticing the problem and bringing the subject
up.
Fortunately, Danny Mayer and I are pretty well-versed in both DNS
and NTP, and it became pretty obvious what this guy's problem was
once we saw the messages saying "; Truncated, retrying in TCP mode."
followed by ";; Connection to 192.168.1.254#53(192.168.1.254) for
pool.ntp.org failed: connection refused."
But these kinds of things are definitely a team effort, and I
can't say enough good things about this team!
