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.

Can you tell us _what_ .gov site?   Do you see the same problem with 9.9.4?
