intermittent resolution

[Con Wieland]

The site I am having issues with are a half a dozen sites at noaa.gov. No I have not tried 9.9.4 when I upgraded 9.8.6 was listed as the current stable version so I went with that.

I can perform a dig +trace and resolve but dig will fail. If I do an rndc reload it will work for some period of time again.  I suspect negative caching but the site has a the ttl set to 60 so I would expect it to resolve again but it doesn't until a reload is preformed,  other sites seem to be effected but I don't know. This is a high visibility site. The only configuration change has been to add RPZ which seems to be working fine.
