You know you have a problem when you have 3 DNS servers for 2 people.

I was waiting for a Windows server to reboot so I took the time to tune my DNS servers at home (ssh + bind + Linux = FTW). I then tested my setup with the DNS benchmark utility from To summarize the output, it turns out (not surprisingly given that there are only two people who use them) that my DNS servers are faster than all of the publicly available ones, including those provided by my ISP. Maybe I have a problem and should find some less geeky hobbies. 

Here is the relevant output from that DNS benchmark utility:

System has multiple redundant nameservers configured. This system is currently configured to use 3 separate nameservers for DNS name resolution. This is in keeping with recommended best practice (of having at least two different nameservers) so that the temporary failure of any single nameserver will not prevent all DNS name resolution.

All system nameservers are alive & replying to queries.   All of this system's 3 nameservers are working and replying to queries. This is terrific because if the system's primary nameserver were to become overloaded or unavailable, even briefly, one or more backup nameservers are standing by ready to supply DNS lookup services.

System nameservers are faster than ALL public alternatives. All of the DNS resolvers your system is using are responding faster than any of the 100% reliable publicly available alternative DNS nameservers this benchmark utility just tested. Therefore, there would be no performance benefit from replacing any of this system's current nameservers with any of those publicly available alternatives.  However, this best performance appraisal assumes that this system's nameservers are 100% reliable.
