With a notable percentage of the NTP servers always indicating leap
it's another instance of "Don't believe everything the internet says."

This begs for a compare and contrast with the validity of other forms
of information distributed around the internet; e.g., DNS. Things like
How automatic is the setup of the service?
What sort of expertise is required for robust configuration?
What are the consequences of getting wrong information?
and other sorts of "How do different things break?"

But I think it's not optimal when a vendor like RedHat finds itself
defining notions of "precise" and "accurate" for its customers
as part of outlining the engineering workarounds. That seems like
a shining example of how all the agencies involved in the definitions
of time scales have left implementation to be Somebody Else's Problem.
