Incidentally, wasn't the original plan for AS9736 to be multi-homed?
It was. Don't get me started on how many times a certain carrier said "we will do it", and then failed utterly to turn the words into action. But mainly the need was for registry services rather than the DNS. In real life, most of the automated stuff was going via the email template, and that could back off and retry quite happily. Without getting into an off-topic discussion of NZ domain name politics, I would suggest that, in hindsight, network availability hasn't been the major reliability issue with domain name registration services. As to the DNS, almost all DNS queries come via caching name servers that are perfectly capable of recording which name servers aren't answering in good time, and directing minimal queries to them. As such there is no loss of service from losing a DNS server or two, and very little performance degradation. That's why we have lots of DNS servers. -- don - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
