The above is what I mean by "banner".

Yours says that it has been 31 hours since four of your servers last 
responded to queries!!  It would appear that "ancalagon.cede." has NEVER 
responded since ntpd was started!

I just did my own ntpq -p and it is now claiming 32 hours since anybody 
responded.  Obviously you have not unplugged your network cable but 
there must be SOME reason why no one will talk to you!

Could you have done something so naughty that your servers have sent you 
the "Kiss Of Death"?
