Hello world, I am by no means an experienced nameserver operator, so chances are that this is a stupid question. Please tell me if that's the case.
Given the crappy resolvers I encountered at many ISPs, I've been running recursive resolvers at quite a few sites. As long as these are up and running, they will reduce the load the internal clients/servers cause on the DNS root and g(TLD) servers, especially in DNS intensive environments like e.g. DNSBL lookups caused on sites receiving a lot of mails. Unfortunately, there are situations that call for those servers to be restarted (updates to system libraries, OS kernel, the DNS software itself). This will increase the load my network causes on the global DNS infrastructure. Are there any recommendations on how to deal with this situations with regards to not putting more of a strain on the root/(g)TLD servers than absolutely necessary?
