I Cannot SSH into My Server Anymore (and That's Fine)
To kick off 2026, I had clear objectives in mind: decommissioning my trusty VPS and setting up its successor. Embracing a complete paradigm shift, I built myself a container-centric, declarative, and low-maintenance setup for the years to come.

Helping to secure internet routing
The internet works reliably, in large part, on the basis of a key technology called Border Gateway Protocol (BGP). BGP is a means by which all junction points on the internet (routers) communicate with each other to dynamically establish the correct (and correctly weighted) paths that network packets should follow to…

Bits on the Wire
Exactly 100% of everything on the Internet involves exchanging messages which represent items of interest to humans. These items can be classified into three baskets: One for “media” (images, sound, video), one for text (HTML, PDF, XML), and one for “objects” (chat messages, payments, love poems, order statuses). This…

Where is all of the Fediverse?
Spurred on by the problems at Twitter, a lot of my social media timeline has “moved out” of Twitter/“X” on to what people mostly describe as mastodon or the “fediverse”. The fediverse being the collection of decentralised “instances” (aka servers) sometimes using different software but speaking a common protocol…

Go HTTPS Servers with TLS
This post is a basic introduction to running HTTPS servers and clients in Go using TLS. It assumes some familiarity with public-key crypto. Feel free to check out my earlier posts about RSA and the Diffie-Hellman Key Exchange ; TLS uses the elliptic-curve version of Diffie-Hellman. I won't be covering how the protocol…

Flat Datacenter Networks at Scale at Amazon
The research roots of finding “optimal routing” networks trace back to the late 1970s. Mathematicians defined special kinds of networks called “expanders“. These are graphs with strong connectivity properties guaranteeing no subset of vertices can be isolated from the rest. In 1976, Leslie Valiant gave one of the…

Goodbye, OpenStack
I just removed myself from every OpenStack mailing list and meetup. I’m sure I’ll still use it, but I don’t see myself as part of that community any longer. When I was at DreamHost, I really felt like part of that community and that I could help make it better. However, in the three years since I’ve left DreamHost, I…

AWS VPC Traffic Mirroring

In addition to simply keeping it up and running, you need to keep an ever-watchful eye out for unusual traffic patterns or content that could signify a network intrusion, a compromised instance, or some other anomaly. VPC Traffic Mirroring Today we are launching VPC…

Calling time on DNSSEC: The costs exceed the benefits
I’m calling time on DNSSEC. Last week, prompted by a change in my DNS hosting setup, I began removing it from the few personal zones I had signed. Then this Monday the .nz ccTLD experienced a multi-day availability incident triggered by the annual DNSSEC key rotation process. This incident broke several of my unsigned…
