Dear Artur Romao, I'm glad to contact you, acting on request of the ripe dns working group which, during the last RIPE meeting in Amsterdam, discussed about DNS failures and made a proposal as stated in the following excerpt from the minutes: {...} Some people do not watch their name servers: it happens that some name servers are left unattended and fail without anyone noticing. This has an impact on the performance and reliability of the overall name service. People should watch their name servers and their zones on their primary and secondaries. At least the 'host' command can be used with the '-C' option to do this at regular intervals. During the plenary session someone remembered the existance of RFC1713 A. Romao, "Tools for DNS debugging", which is usually referred to as the guide for DNS administrators and suggested to ask the author to include such recommendation.
