		<description><![CDATA[At NANOG 96, the AI boom dominated discussions as firms race to build gigawatt-scale data centres packed with advanced GPUs, liquid cooling, and lossless networks, raising fears of overinvestment, neglected security priorities, and a looming infrastructure bubble. <a href="https://circleid.com/postsnanog-96-gigawatt-ai-data-centres-and-the-risk-of-a-bubble">More...</a>]]></description>

		<link>https://circleid.com/postsinternet-evolution-moores-law-addressing-architectures-and-the-future-of-internet-scale</link>
		<description><![CDATA[The Internet has evolved from a scarcity-driven system into one defined by abundance, reshaping infrastructure, governance, and economic models while challenging long-held assumptions about addressing, network roles, and the future of protocol design. <a href="https://circleid.com/postsinternet-evolution-moores-law-addressing-architectures-and-the-future-of-internet-scale">More...</a>]]></description>

		<title> Lost in Space: The Limits of Geolocation in a Satellite-Connected World (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/postslimits-of-geolocation-in-a-satellite-connected-world</guid>
		<link>https://circleid.com/postslimits-of-geolocation-in-a-satellite-connected-world</link>
		<description><![CDATA[Starlink's global reach is distorting conventional IP geolocation, blurring national boundaries and skewing internet usage data. As satellites replace cables, measuring users' precise locations has become an increasingly uncertain and politically charged task. <a href="https://circleid.com/postslimits-of-geolocation-in-a-satellite-connected-world">More...</a>]]></description>

		<title> The Governance of the Root of the DNS (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/poststhe-governance-of-the-root-of-the-dns</guid>
		<link>https://circleid.com/poststhe-governance-of-the-root-of-the-dns</link>
		<description><![CDATA[The arrangements regarding the composition and organisation of the provision and operation of authoritative root servers are one of the more long-lasting aspects of the public Internet. In the late 1980s, Jon Postel, as the IANA, worked with a small set of interested organisations to provide this service. It was informally arranged, without contracts and without payment of any form. <a href="https://circleid.com/poststhe-governance-of-the-root-of-the-dns">More...</a>]]></description>

		<title> Ossification and the Internet (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/postsossification-and-the-internet</guid>
		<link>https://circleid.com/postsossification-and-the-internet</link>
		<description><![CDATA[Networks are typically built to provide certain services at an expected scale. The rationale for this focused objective is entirely reasonable: to overachieve would be inefficient and costly. So, we build service infrastructure to a level of sufficient capability to meet expectations and no more. In ideal conditions, this leads to a widely deployed and highly efficient infrastructure that is capable of supporting a single service profile. <a href="https://circleid.com/postsossification-and-the-internet">More...</a>]]></description>

		<title> Jevons Paradox and Internet Centrality (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/postsjevons-paradox-and-internet-centrality</guid>
		<link>https://circleid.com/postsjevons-paradox-and-internet-centrality</link>
		<description><![CDATA[The story of computing and communications over the past eighty years has been a story of quite astounding improvements in the capability, cost and efficiency of computers and communications. If the same efficiency improvements had been made in the automobile industry cars would cost a couple of dollars, would cost fractions of a cent to use for trips, and be capable of travelling at speeds probably approaching the speed of light! <a href="https://circleid.com/postsjevons-paradox-and-internet-centrality">More...</a>]]></description>

		<title> Internet Governance - the End of Multi-Stakeholderism? (Featured Blog)</title>

		<link>https://circleid.com/postsinternet-governance-the-end-of-multi-stakeholderism</link>
		<description><![CDATA[When the Internet outgrew its academic and research roots and gained some prominence and momentum in the broader telecommunications environment, its proponents found themselves in opposition to many of the established practices of international telecommunications arrangements and even in opposition to the principles that lie behind these arrangements.  <a href="https://circleid.com/postsinternet-governance-the-end-of-multi-stakeholderism">More...</a>]]></description>

		<title> The Missing Data: Measuring ISP User Populations (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/poststhe-missing-data-measuring-isp-user-populations</guid>
		<link>https://circleid.com/poststhe-missing-data-measuring-isp-user-populations</link>
		<description><![CDATA[In our physical world, census information is used to inform the planning processes behind the provision of infrastructure, such as schools, hospitals, housing, and similar. It can be used to assess the impact of natural disasters or to understand a society's needs in terms of food and energy security. Demographic data is also used to inform investment and business decisions. You'd think that the Internet itself would be awash with similar information. <a href="https://circleid.com/poststhe-missing-data-measuring-isp-user-populations">More...</a>]]></description>

		<title> The Evolution of DNS: Adapting to the Changing Internet Landscape (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20240627-the-evolution-of-dns-adapting-to-the-changing-internet-landscape</guid>
		<link>https://circleid.com/posts20240627-the-evolution-of-dns-adapting-to-the-changing-internet-landscape</link>
		<description><![CDATA[The DNS is a crucial part of today's Internet. With the fracturing of the network's address space as a byproduct of IPv4 address run down and the protracted IPv6 transition the Internet's name space is now the defining attribute of the Internet that makes it one network. However, the DNS is not a rigid and unchanging technology. It has changed considerably over the lifetime of the Internet and here I'd like to look at what's changed and what's remained the same. <a href="https://circleid.com/posts20240627-the-evolution-of-dns-adapting-to-the-changing-internet-landscape">More...</a>]]></description>

		<title> A Transport Protocol’s Perspective on Optimizing Starlink Performance (Featured Blog)</title>

		<link>https://circleid.com/posts20240517-transport-protocol-perspective-on-optimizing-starlink-performance</link>
		<description><![CDATA[<a href="https://circleid.com/guides/starlink-internet-service"></a>Digital communications systems always represent a collection of design trade-offs. Maximizing one characteristic of a system may impair others, and various communications services may choose to optimize different performance parameters based on the intersection of these design decisions with the physical characteristics of the communications medium. <a href="https://circleid.com/posts20240517-transport-protocol-perspective-on-optimizing-starlink-performance">More...</a>]]></description>

		<link>https://circleid.com/posts20240314-digital-sovereignty-and-internet-standards</link>
		<description><![CDATA[There have been a number of occasions when the Internet Engineering Task Force (IETF) has made a principled decision upholding users' expectations of privacy in their use of IETF-standardised technologies. (Either that, or they were applying their own somewhat liberal collective bias and to the technologies they were working on!) The first major such incident that I can recall is the IETF's response to the US CALEA measures. <a href="https://circleid.com/posts20240314-digital-sovereignty-and-internet-standards">More...</a>]]></description>

		<link>https://circleid.com/posts20231122-call-the-routing-police</link>
		<description><![CDATA[There was a somewhat unfortunate outage for a major communications service provider in Australia, Optus, in mid-November. It appears that one of their peer Border Gateway Protocol (BGP) networks mistakenly advertised a very large route collection to the Optus BGP network, which caused the routers to malfunction in some manner. <a href="https://circleid.com/posts20231122-call-the-routing-police">More...</a>]]></description>

		<link>https://circleid.com/posts20231025-notes-from-nanog-89-trust-and-network-infrastructure</link>
		<description><![CDATA[Trust is such a difficult concept in any context, and certainly, computer networks are no exception. How can you be assured that your network infrastructure is running on authentic platforms, both hardware and software and its operation has not been compromised in any way? <a href="https://circleid.com/posts20231025-notes-from-nanog-89-trust-and-network-infrastructure">More...</a>]]></description>

		<link>https://circleid.com/posts20231019-internet-governance-in-2023</link>
		<description><![CDATA[It's been an interesting couple of weeks for me, in mid-October 2023. I presented in a couple of panels at the 18th Internet Governance Forum meeting, held in Kyoto, Japan, and I also listened in to a couple of sessions in their packed agenda. The following week, I followed the presentations at NANOG 89, the meeting of the North American Network Operator's Group, and listened to a presentation by John Curran, the President and CEO of ARIN, where he gave his impressions of the current state of Internet Governance. <a href="https://circleid.com/posts20231019-internet-governance-in-2023">More...</a>]]></description>
