Extreme weather prompts revision of cooling strategies

Following warnings from scientists that current climate conditions are brewing extreme weather in the months ahead, Aggreko, a British temporary power generation and temperature control company, says it is calling upon data centre managers to revise their cooling strategies ahead of time or face the consequences. Global sea temperatures of 21°C were reported last month - the second highest on record for the month of April - with scientists now pointing to another El Niño warming cycle that could significantly intensify extreme weather. These temperatures are marginally lower the 21.04°C recorded in April 2024 ahead of the last El Niño weather event, which ended up being the fourth warmest year on record for the UK. With a long, hot summer potentially in store, Chris Smith, Head of Temperature Control at Aggreko, says he is urging the data centre sector to review its cooling infrastructure before the heatwave arrives. He suggests, “We need only look back at 2024 to see what El Niño might have in store for us this year. Summer temperatures regularly exceeded 30°C, placing immense pressure on data centre cooling infrastructure and even leading to full-blown equipment failure in worst-case scenarios. “The reality is: current cooling strategies simply aren’t designed to deal with this kind of weather or to operate in these temperature ranges. For this reason, now is the time to start reviewing current cooling infrastructure to assess whether it’s still fit for purpose so the right measures can be brought in ahead of time. “The main thing to look out for is ageing assets, as these are at the greatest risk of lower efficiency, overheating, and failure. Engaging with a specialist temperature control partner can help implement temporary cooling and industrial HVAC solutions to bridge gaps during equipment failures, manage seasonal demand peaks, and provide N+1 redundancy for greater operational resilience.” Data centre cooling under pressure With rack densities on the rise, data centre cooling infrastructure is arguably under greater pressure than ever before, with the cost of outages reportedly becoming more expensive. In the Uptime Institute’s 2026 outage analysis, cooling accounted for 14% of all impactful outages - the second biggest contributor behind power - while one fifth of respondents stated that their most recent outage cost more than $1 million (£745,000). In the face of this challenge, Aggreko believes hybridised packages consisting of battery energy storage systems (BESS) and temporary chillers or cold storage units are becoming an increasingly popular option for the data centre industry. Here, the company notes, the chiller or cold storage unit can provide scalable, supplementary cooling capacity, with the BESS powering the package while enhancing efficiency, reducing costs, minimising environmental impact, and offering near-silent operation versus a standard generator. Chris continues, “While we’ll have to wait and see what the summer has planned for us, now is nonetheless a prime time to re-evaluate cooling strategies and identify where efficiency gains can be made. "Procuring temporary cooling from a third-party specialist not only allows access to the latest, high-efficiency technology, but also opens the door to a number of creative solutions, such a hybridisation, which just aren’t feasible in-house. “While cooling is just one of the challenges that data centre managers have to contend with at the moment, the gains this can deliver, alongside the resilience it provides against the threat of outages, mean that this is more than a worthwhile operational solution.” For more from Aggreko, click here.

Eastern Light expands Nordic fibre capacity

Eastern Light, a Stockholm-based independent operator building and owning long-haul dark fibre submarine cable routes, has started construction of the Nordic Corridor, a new subsea fibre cable system connecting Sweden and Finland. The project includes the SF-II subsea connection and represents an investment of approximately €30 million (£26 million). Combined with the company’s existing SF-I cable system, the Nordic Corridor is intended to increase digital communications capacity between the two countries. Eastern Light currently operates the SF-I subsea cable between Sweden and Finland, which contains 144 fibres. The new SF-II system will add a further 288 fibres through a combination of terrestrial and subsea infrastructure. According to the company, the expanded system is designed to meet increasing demand for digital capacity across the Nordic and Baltic regions, particularly as data centre development accelerates. Mikael Vesterlund, COO of Eastern Light, says, “We are seeing rapidly growing demand for digital capacity in the Baltic Sea region, driven primarily by investments in data centres across the Nordics. "Several of the existing cable systems are old and are beginning to reach full utilisation. That is why we need to expand digital capacity between the countries. The Nordic Corridor is an important step in meeting this development.” New cable route designed around resilience Eastern Light says the SF-II deployment will take place in several phases. The first stage, extending to Finnish territorial waters near the Åland archipelago, was completed in May. The company states that the cable route has been designed to remain within national waters, reducing risks associated with international routes and simplifying future repair work if required. Eastern Light also says the Nordic Corridor is owned and financed by Nordic stakeholders. Mikael continues, “The Nordic Corridor is a project of critical importance to society. In the event of security incidents, data must be able to take alternative routes. "That is why we are now strengthening the robustness of the system by building a new fibre connection between Sweden and Finland. More cables are needed.” The SF-II project will span approximately 480km and has an estimated operational lifespan of around 50 years. The subsea cable itself will weigh approximately 566 metric tonnes.

'External threats a rising cause of outages for data centres'

External infrastructure failures and outages linked to fibre and connectivity issues are becoming more prominent for data centres, according to new research from the Uptime Institute, a US-based independent data centre standards and certification body. Despite that, on-site outages for data centres have declined for the fifth consecutive year, with approximately one in 10 noting that their last outages had a serious or severe impact. The cost of major outages continued to rise, with 57% stating that their most recent major outage cost over $100,000 (£74,800) and one in five reporting a cost of over $1 million (£748,000). Richard Petrie, CTO of the London Internet Exchange (LINX), comments, “Networking and connectivity continue to sit at the top of the most common causes of IT outages, reinforcing the importance of resilience in this area. "As organisations face growing pressure from network congestion, external threats, and increasing reliance on third-party providers, resilience across both network and data centre infrastructure is becoming critical. "While it’s encouraging to see on-site outages declining as infrastructure providers continue to prioritise resilience, the risks posed by external failures mean organisations still need robust redundancy policies in place for when outages do occur. "The backbone of a strong redundancy strategy is a secondary fabric that allows data to be rerouted during periods of disruption or risk, helping organisations remain operational even when the primary network is compromised. "By providing multiple options to route traffic, organisations can strengthen resilience and help networks stay online.” Power failures a contributing a factor The leading cause of impactful outages was power, with failures involving UPS systems, transfer switches, and generators remaining prominent. Worsening grid constraints and high-density workloads were also found to contribute to outages as a newer challenge. To adapt, the research outlined that operators are adapting investment strategies towards automation and control systems in order to manage complexity, despite acknowledging that more automation can cause different classes of problems. In line with the causes of outages, resilience assessments were found to focus more on internal systems than on external and systemic risks. Andy Lawrence, founding member and Executive Director of Uptime Intelligence, says, “Outages overall have slowed down and, overall, digital infrastructure is remarkably resilient. But further resiliency gains are becoming harder to achieve. “We believe that over time, failures will increasingly not be the result of a single point of failure, but instead be linked to complex interactions between systems, including software, networks, and external dependencies. "While site-based electrical and mechanical infrastructure remain a critical building block that needs to be resilient, digital infrastructure is becoming more distributed with outages originating outside the data centre, including those tied to power availability, network connectivity, or the reliance on external cloud services playing a larger role.”
