Global data rush paving the way for boom in data centre business in Europe

Investments in the industry more than doubled in 2021 to $59.5 billion

Bombproof buildings, biometric security passes and financial trading at the speed of light: welcome to data centres, a booming global industry that is hosting more of the world's money, entertainment and energy use than ever.

In the foothills of the Italian Alps, one of Europe’s newest data hubs is a prime example of how these boxy buildings have become cornerstones of the economy. Since June, Euronext NV has aided a quarter of European equities trading in the former textile town of Ponte San Pietro.

Within the building’s 800km network of cables, banks such as Goldman Sachs Group and JP Morgan Chase shoot trading data at one another’s servers within 20 microseconds, or millionths of a second.

“It used to be a big noisy room with people buying and selling. Now it’s a big noisy room with servers,” Manuel Bento, Euronext’s chief operating officer, said in an interview, referring to the changes in trading culture. “Speed matters.”

The data centre is now handling average volumes of €13 billion ($13.7 billion) each day — roughly twice that of Deutsche Boerse AG or London Stock Exchange Group Plc, said Stephane Boujnah, Euronext’s chief executive.

These are trades that, before Brexit, took place in an equally imposing warehouse a few kilometres east of London. It took a little more than a year to shift the operation to Italy.

The new site, about an hour from Milan, is part of an industry that is accelerating as firms digitise their services and daily life shifts online.

Every time someone reads an email, streams a movie or reads a tweet, the chances are they passed through a building like this. Every time something happens on “the cloud”, it is happening in someone’s data centre.

Investments in the industry globally more than doubled in 2021 to $59.5 billion, research by the law firm DLA Piper reported, driven by the growth of firms such as Facebook parent Meta Platforms, Google’s Alphabet and Microsoft.

Investment this year had already surged to $21.3 billion by June 7, doubling the record set last year. This demand is also firing up businesses that supply equipment to data centres, including chipmaker Nvidia and network specialist Cisco Systems.

“There’s a massive explosion of content and all that has to be resided and stored somewhere,” said Dalmar Sheikh, director and global head of data centre operations at infrastructure investor Actis. The firm has data centres in Nigeria and China and is building more in South Korea and across Africa.

For finance companies, the attraction of using data centres can lie in faster trading times — particularly if they can rent a spot in a data centre close to its market counterparties, known as colocation.

Firms that need huge computing power, such as payment processors or Bitcoin miners, can get greater flexibility from a data centre than their own hardware.

To be sure, trading in data centres is not for everyone: automated, high-speed algorithms can distort the market, while fees for data and colocation services can be hugely expensive, said Chris Jackson, head of equities for EMEA at Liquidnet Europe, which operates dark pools where firms can trade more slowly and discreetly.

''We would argue that it has created a hostile market for legitimate long-term institutional investors,” said Mr Jackson.

Still, even for tasks that tolerate slower processing times, data centres are offering modern kit that, unlike firms’ own legacy servers running ancient code, allows them to outsource worries about maintenance and security.

But, like trades on screens, these matters have to be managed somewhere in the real world. Growing concerns about energy usage in data centres have halted some projects in the Netherlands, where the government imposed a nine-month block on permits for sites larger than 10 hectares.

Centralised data centres are, in theory, safer against cyber-security incidents, since they are protected by one specialist company, rather than by each business trying to run its own servers.

However, “I wouldn’t use the word ‘safe.’ Nothing in this world is safe”, said Beatriz Sanz Saiz, EY global consulting data and analytics leader.

Euronext moved its hub to Italy partly due to Brexit, and relocated from Basildon, a town outside of London.

“Post-Brexit we wanted all data centres in the EU to have their core infrastructure in Europe,” said chief executive Mr Boujnah. “We didn’t know what the direction of travel was in the UK and didn’t want to take any regulatory risks.”

It previously rented space in Basildon from Intercontinental Exchange, which owns the New York Stock Exchange. It is a largely windowless building in a maze of industrial parks near bathroom showrooms, tractor dealerships and small-time law firms.

ICE’s data centre is difficult to miss at 30,000 square metres, or four times the size of football pitch. Inside, banks trade fixed-income derivatives such as gilts and Euribor futures, with hundreds of fibre optic cables running west to London, south via the English channel to Europe, and under the Atlantic to New York.

“People who want to be in Basildon want premium access to the trading engine and to the data that is published locally, and there is nothing that provides faster access than colocation,” said Nicolas Bonnet, director of global connectivity product at ICE.

At Telehouse, a short distance from the O2 arena in the Docklands area of east London, vibration wire around the site alerts 24/7 security staff to intruders.

Workers use biometric fingerprint recognition to enter key rooms, parts of the building are bombproof and the firm works closely with police and counter-terrorism officials.

The goal is to protect the data of clients including Amazon and Microsoft, whose servers are identified by code, rather than by their names, to lower the risk of data breaches.

“We are designed to operate and keep services running in many, many different failure scenarios,” said Paul Lewis, senior operations director at Telehouse Europe. “We don’t want people coming in who shouldn’t be here and there are a lot of checks and balances.”

Clients rent a space similar to a gym locker that is connected via yellow cables. The activity in all these lockers can send the centre's temperature soaring towards 40°C, requiring Telehouse to run air cooling.

There are enough backup generators and fuel supplies to keep the building running through a 36-hour power cut.

Telehouse already operates five data centres in London and is planning to knock down a disused hotel next year to build a sixth, which could cost hundreds of millions of pounds.

One of the biggest concerns about the industry is its environmental impact. These buildings use 1 per cent of global energy in 2021, according to the International Energy Agency, and in Ireland, this has more than tripled to 14 per cent since 2015.

In Denmark, it is projected to triple to 7 per cent by 2025.

In Norway, data centre operator Green Mountain cools one of its sites with water drawn from a nearby 150-metre-deep fjord. It is also planning to take the newly heated water and pump it into a lobster farm being built on its site, said marketing manager Mette Gulbrandsen.

Euronext says it may have another solution. The firm generates power from solar panels and hydroelectricity on the Brembo River that flows down from the Bergamo Alps.

“Data centres are really the major problem when it comes to carbon footprint reduction in the digital economy,” said Mr Boujnah. “Our carbon footprint is neutral.”
