Sustainability needs to be applied at all levels of the data center industry, and we are not doing enough, says John Booth of Carbon3IT.  In this episode of Zero Downtime, we sit down with sustainability consultant John Booth to talk about how he got where he is in his career, and the fundamental sustainability issues that he is seeing in the data center industry.  We also talk about a past trip to Belarus that proved more exciting than expected. Tune in now for the latest episode.

Bringing the L to FLAP-D, the UK has a prominent data center market. But like all other tier-one markets, London is struggling with space and power capacity. Because of this, the UK's data center industry will have to diversify, all while meeting increasingly regimented regulations. In this episode, we talk to trade association TechUK's Luisa Cardani about what the UK's data center industry is currently experiencing, from upcoming rules and regulations to emerging new markets, to the...

Oxide Computer has been rebuilding the rack. In this podcast, CTO Bryan Cantrill tells us why.  The data center industry has been building its own infrastructure for years, with the wrong components. Servers weren't designed to be operated in data centers, and the 1U rack unit is the wrong size, because of simple science. Part of the success of the cloud is that it takes that integration away, and gives users an easily consumed set of virtual servers and elastic infrastructure. But it...

Think hard drives have hit their storage limits, and should be replaced by solid-state units? You could be wrong.  Hard drives have been holding our data for nearly 70 years since IBM created the 350, which stored something like 4 Mbyte on dozens of spinning disks in a unit the size of a washing machine. Today's devices are orders of magnitude better on every axis including price, capacity, size, and performance. But solid-state providers say it's time they moved over to make way for...

In this episode of Zero Downtime, we break down the fundamentals of quantum computing - the different approaches out there, the challenges to bringing it into a widespread commercial reality, and the potential use cases that quantum may help with. To help divulge this, we speak to QuEra's Yuval Boger who shares a little about the company's experience with the technology, including how we can go about deploying quantum computers inside data centers.

25 years ago, the first content delivery networks (CDNs) emerged, to solve a specific problem - how to make web pages load faster. More than two decades later, 72 percent of Internet content is delivered through CDNs. But the companies involved are still almost invisible - until something goes wrong. In 2021, in a series of outages, large numbers of unrelated websites all went out of action at the same time. It turned out that these sites had all come to rely on the same CDNs,...

Europe has an Energy Efficiency Directive, Germany has an Energy Efficiency Act, and operators there can be fined for inefficiency. Meanwhile, Amsterdam has declared war on sleeping servers, and set limits on where facilities can be built. Across Europe, in response to congested electric grids and shortages of land, local governments are stepping in to regulate data centers. Sometimes they want them to be greener, sometimes they want them to be quieter, and sometimes they just want them...

At the start of 2023, Yuval Bachar told us about his latest project - to build off-grid, hydrogen-powered data centers. As 2023 came to an end, he was back to tell us he'd done it. He's got 1MW of capacity fed by hydrogen in Mountain View California, and he's telling potential customers he can build the same thing anywhere you can get hydrogen shipped by pipe or tanker.  He's keen on the benefits. No long waits for power distribution, no struggles getting permits for diesel. And the...

Ever wonder what it would be like to be a CEO at a telecom company in a country that is at war?That’s been the reality on a couple of occasions for Ineke Botter, who has headed telecom companies in Kosovo and Lebanon. Her career has taken across Europe and beyond, spanning more than 30 years. She’s even worked in the data center industry too. Listen to find out more about Ineke’s incredible journey into telecoms.

The European data center market has a forecasted take-up of 440MW for 2023. But within the context of erratic power availability, moratoriums, and the need to move to renewable energy, the FLAP-D markets are facing several challenges. In this episode we talk to Neal Kalita about the obstacles facing those looking to build in Europe, and what the future holds for the region. Tune in for the conversation where we find the solution to keeping up with the pace of demand while prioritizing...

Data centers need to be more sustainable, but finding consistent and powerful energy resources can be a challenge. Increasingly, we are seeing nuclear entering the conversation, in the form of Small Modular Reactors (SMRs). But these aren't without their own controversies. In this episode, we talk with Compass Datacenters' Tony Grayson to discuss the future of SMRs, the challenges and opportunities, and the role we can expect them to play in the world of data centers.

Artificial intelligence could grow from almost nothing to using half a percent of the world's electrical power within five years, according to Alex de Vries of Digiconomist. That's a crazy rate of growth, but it's not unprecedented. Bitcoin followed almost exactly the same trajectory, expanding from nothing to a sector whose energy use is comparable with that of regular data centers. But the similarities end there, says de Vries, who provided the reliable tracking data for the growth of...

We talk to Bill Kleyman, now at machine learning company Neu.ro, about his lengthy data center career. How did he get into the sector, what did he learn at Switch, and how does he balance life and travel? Tune in to find out.

Data centers have outgrown their anonymity. They are large enough consumers of energy and space, that they have to enter the political landscape and justify their existence. But how do we know if a data really brings benefits to its location? In some places (like London), it appears that they soak up grid connection capacity and block housing projects. In others (like Denmark and Ireland) they use renewable energy and jeopardize local decarbonization targets.  It's not easy to know the net...

Ever wondered about the practical challenges of connecting our continents? In this podcast episode, we talk with Exa Infrastructure's Elena Badiola about the process of getting subsea cables underwater: from environmental surveys to climate change, to funding challenges. Elena also shares her experience of living on a cable ship for five weeks after an earthquake caused an outage - and how a military coup almost stopped her from getting back home.

In 2022, Mark Monroe's podcast about hydrogen was one of our most popular podcasts ever. At Microsoft, Mark had just made a prototype hydrogen fuel cell UPS system that could potentially replace diesel generators to provide low-carbon backup power at data centers. One year on, he's back for some more detail. A hydrogen economy will need a distribution system - but will that look like a power network, a gas grid, or a system of trucks?  Data centers won't be the first big users of...

If you want to make infrastructure sustainable, you need to be very careful what words you use. That's what Hunter Vaughan and Nicole Starosielski found, through their involvement in a project to make subsea cables sustainable. Words like "sustainability" and "climate neutral" can mean different things, depending on who is talking. And if what you say is vague, then your efforts to be sustainable can get misdirected, or diverted into greenwash, or simply end up (like the words)...

If you think transitioning the tech sector to net zero is all about renewable energy and heat reuse, think again. Small changes in software could make entire data centers redundant - for a much bigger saving for the planet.  Green Software is not just about more efficient code, says Anne Currie. Rewriting everything in C might cut energy use - but it would destroy your company.   As a leader in the Green Software Foundation, and a seasoned green developer and entrepreneur, Anne has much...

How does the Internet keep running? A close-knit community of engineers has been developing and supporting the protocols that support it for more than forty years. During that time, new Internet services have emerged and scaled beyond recognition, and new features have been added, all without breaking the whole system.  Mirjam Kuhne has been closely involved with this for 20 years, and in 2020 became chair of the European forum for Internet development -  RIPE (Réseaux IP Européens, French...

The global interests of the mobile industry are represented by the GSM Association (GSMA).  This governing body was established in 1995 to support mobile operators using the GSM (Global System for Mobile Communications) standard for cellular networks.  It has become synonymous with the mobile industry and has driven it forward through industry programs, working groups, and initiatives.  The GSMA’s legacy has even inspired something similar but for broadband instead, with Martin Creaner,...

Quantum computing is still pretty mysterious, but data center operators have real questions: when will they need installation and support? And how much cooling will they need? Chris Monroe, chief scientist at IonQ, gives us the answers, along with plenty of other solid facts about an emerging technology that can seem as illusory as Schrodinger's cat.  It turns out that quantum computing is reaching a point where lots of us could soon start to use it. The market may have to choose from an...

There has been an ongoing issue with the representation of women in the tech industry, but why? In this episode, we talk to Kelley Mullick about her career to date, the factors that have helped her get to where she is, and the importance of supporting and empowering women to pursue these careers so they can find confidence within themselves. We also talk a little about her recent job change from Intel to vice president of technology advancement and alliances at Iceotope - what drew her to...

Having trouble finding a location for your data center project? This DCD podcast could have the answer. Build underground.  Andrew Bourget of Swiss engineering firm Eccus has a design for a 2MW data center built in an underground tunnel - and he can dig that tunnel wherever you want it, even under existing buildings.  The way he tells it, tunneling is the future. There's no planning permission required, and you can build under your existing facility. You can migrate underground, and still...

In March this year, a swimming pool in Devon, UK, was the unlikely setting for the most widely covered data center story (so far) of 2023.  A small immersion-cooled high-performance computing module from Deep Green is giving its heat to the swimming pool, saving Exmouth Leisure Centres £20,000 ($24,000) per year. It's not the first time data center waste heat has been harnessed. It's not even the first time it has heated a swimming pool. But Deep Green CEO Mark Bjornsgaard tells us that,...
