As a collection of inter-twined markets, aspects of the Internet have been prone to excessive market distortions where one, or a small clique, of providers in market sector become completely dominant to the extent that there is no effective competition and no possibility of admitting additional market entrants.

NZNOG 2026 was held in Christchurch in March 2026. The NZ national community has a long track record of innovation, both in technology and in the underlying investment models for its network infrastructure. Here's a summary of some of the sessions that I found to be of interest.

It's fading from our collective memory, but almost thirty years ago the global IT industry was gripped by Y2K fever. Another version of the counter rollover problem is coming back in 2036, 2038 and 2040. Hopefully we will avoid a large amount of hysteria this time around!

For some time, I have been looking after a routing analysis report called the "". Here I'd like to explain the reasons for this report, and what is in the report and share some thoughts as to its usefulness today to the Internet routing community.

Today's digital world relies on a consistent view of the time. We achieve this with the Network Time Protocol (NTP). Given the extent of our reliance on an accurate time base it is surprusing that the NTP protocol has no security mechanisms to protect the integrity of time dissemination. Lets look at time, NTP and the recent efforts to add authenticity and temper detection to this protocol.
