authoritative

So recently I was spinning up some new authoritative names servers. I have stuck with bind for authoritative for years because the format of the files and queries is THE standard for DNS zones. IMHO, there are some better resolvers out there but I stick with bind for authoritative. Anyway, on to my issue. The purpose of one of these servers was for reverse DNS. I added the in-addr files and added a few zone files. Things hummed along for a few days...
