[ntp:questions] ntp-b.boulder.nist.gov not synchronized

Thanks for the response.

We are using the other authenticated server. With only one available, 
our redundancy is gone. If NIST could say, for example, that the broken 
server would be fixed come Monday, I'd chill. However, people I've been 
able to contact are saying the only person that knows anything about / 
can do anything with the broken server is out until July.

I'll look into dnssec for one (or more) of the non-authenticated servers.

Thanks for that idea.
