Hunter Newby doesn't claim to have invented the Meet-Me Room, but he created one of the first, in the iconic and historical Manhattan facility, 60 Hudson Street, in about 1998 At the time data centers had separate connections from multiple carriers, and linking between those carriers meant running a link between their connection points - and paying them heavily. Hunter set up a room where the networks all met up for physical (layer 0) connections - and the rest is history. It's a well-documented history because he went on to write a series of magazine articles "Meet Me In New York", "Meet Me In Chicago" etc, about interconnection facilities in major US cities. That series is archived on his site, alongside live data of connections for each of those cities from the open peering resource, PeeringDB. Today, there are still not enough Meet-Me rooms. Some US states with large cloud facilities don't have nearby carrier hotels, so local user traffic has to go out to a city like Chicago and back. Hunter's wants to foster neutral carrier hotels where there are none. Why is 60 Hudson Street the Ellis Island of the Internet? And did Hunter ever write "Meet Me In St Louis"?

Join us for an extended discussion with CTO and founder of North American Access Technologies Julius Neudorfer about the history of liquid cooling, and where he sees the market developing in the future.

Formed by DigitalBridge and Liberty Global, AtlasEdge has quickly become one of the Edge industry's largest players. We chat to COO Zahl Limbuwala about how it defines the Edge and where it places its servers.

For years, operators have been trying to make their data centers more efficient by optimizing the cooling and power distribution in the facility - and have more or less ignored the IT equipment in the racks. PUE - the most popular data center metric - simply optimized the ancillary equipment, trying to approach a "perfect" figure of 1.0, where all the power goes into the rack. But what if you could measure the power used by your IT equipment, run comparative tests, and find out how to reconfigure, replace or update your hardware to improve energy efficiency? Rich Kenny claims to be able to do that. Interact started as a project by refurbished hardware supplier TechBuyer, aiming to prove that refurbished hardware could be as good as new kit, and grew into a consultancy that compares hardware configurations, and gives guidance on how to do more with less hardware. Server manufacturers do their business on the basis that new hardware is always more efficient than old hardware, and colo providers would rather you didn't find out that you could do away with half the racks you are renting. Kenny is shining a light into a dark corner that has not had enough exposure, dissecting the 1 in that PUE figure. He could be about to step on some industry toes...

In this episode, we talk to Cloudflare's CTO John Graham-Cumming about how to respond to an outage at your company. We also discuss why the company bans the use of the word "Edge," and talk about the company's 'Supercloud.'

Can light be used to compute? We talk to Nick Harris, CEO of chip startup Lightmatter, about how the company hopes to harness photons for AI computing and as a data center interconnect.

What does a technologist do at a real estate company? We talk to Digital Realty's CTO Chris Sharp about the importance of understanding both bits and bricks, discuss the company's interconnection efforts, and do a quickfire round on which future technologies will transform the data center.

Most people think the Internet of Things is a recent idea, maybe dating to around the year 2000.  In fact, the idea is some 15 years older than that. In 1985, the Internet was officially two years old. It linked up some 2000 hosts, and a handful of people used email. In that year, cellular phones were the size of bricks, and almost no one had one. And yet, in 1985, Peter T Lewis predicted the two could be combined, so devices could communicate over wireless links. "I predict that not only humans, but machines and other things will interactively communicate via the Internet," he said. "The Internet of Things, or IoT, is the integration of people, processes, and technology with connectable devices and sensors to enable remote monitoring, status, manipulation, and evaluation of trends of such devices." Listen to our podcast to find out how Lewis made this astonishingly accurate prediction, years ahead of his time. in a speech to the Congressional Black Caucus Foundation in 1985. We also find out how his ideas were almost forgotten, and what he thinks of today's IoT.

After a hiatus of several years, climate change policy is taking off in the US, with the Biden-Harris Administration using the Inflation Reduction Act and the Energy Earthshot to accelerate the clean energy economy. But data center energy policy goes back a lot further than that. Stephen Harper, Intel's Global Director, Environment and Energy Policy, was there 20 years ago when data centers first came onto the climate change radar, and he's been tracking progress since then. As well as their own emissions "footprint", data centers have a positive impact on emissions elsewhere, known as the environmental "handprint" But how do we measure that handprint, and set it against the negative impact of infrastructure. And coming after this backstory, just what impact of these Biden-Harris initiatives have? DCD speaks to Stephen about the likely impact of historic climate legislation for the digital infrastructure sector.

Efforts to reduce the environmental impact of our digital world tend to start with the cooling systems at data centers, and rarely get any further. The tech industry created PUE as a simple metric which could express how efficiently power is delivered to the racks, but did not consider what happens to that power when it gets there. That’s not good enough, because poorly written software could be wasting that power in unnecessary loops and fruitless calculations. The Green Software Foundation has emerged to propose a measure of Software Carbon Intensity that will tell developers if their software is a good planetary citizen. But this is an issue that gets more complex, the more you look at it. Software that completes quickly must save energy, but what if the software is running on multiple hardware platforms? What about the embodied energy of the hardware you choose for it? David Mytton is Co-founder & CEO of Console, a company that makes tools for developers. He’s also looked at the energy used in technology, bothy at Imperial College and at the Uptime Institute. He’s now working on a PhD in sustainable computing at the University of Oxford. He talks to us about the prospects for Green Software finding its way from academic research, through sponsorship by large vendors, into the hands of developers and consumers.
