Krystal warns UK data centres face extreme weather risks
Krystal has raised concerns about whether UK data centres are built and operated to withstand periods of extreme weather. The warning comes as data centres are now part of the UK’s Critical National Infrastructure.
The hosting provider is focusing on how resilient facilities are during heatwaves, flooding, water scarcity and pressure on the electricity grid. It argues that outages linked to extreme weather show climate risk is no longer a theoretical issue for the sector.
Recent incidents have brought the issue into sharper focus. The Dawn supercomputer at the University of Cambridge was reportedly knocked offline for nine days during a period of unusually high temperatures. In 2022, record 40C temperatures forced Google and Oracle to shut down parts of their London data centres after cooling systems failed to maintain safe operating temperatures.
That same summer, cooling system failures at Guy’s and St Thomas’ NHS Foundation Trust left staff locked out of patient records, with the disruption estimated to have cost the NHS £1.4 million. The incidents have intensified questions about infrastructure resilience as digital systems become more deeply embedded in public services, healthcare and finance.
Climate pressure
Data centres generate substantial heat because servers run continuously, making cooling systems essential to daily operations. Many facilities were designed around older assumptions about British weather, Krystal argues, leaving them under strain as higher temperatures become more common.
In hotter conditions, cooling systems spend less time in their most efficient operating modes and rely more heavily on mechanical cooling, according to the company. That can reduce operational margin during sustained heatwaves and increase the risk of outages if a cooling unit fails.
The pressure extends beyond temperature control. Extreme heat can also reduce the amount of power that overhead transmission lines can safely carry, just as electricity demand rises because of cooling needs across the economy.
If cooling systems and grid supply come under stress at the same time, a data centre can lose service quickly. Flooding presents a separate risk, especially for sites in flood-prone areas or those served by ageing drainage systems, because water penetration can affect power, cooling equipment and hardware at once.
Old and new sites
Newer facilities in the UK are more likely to be designed with higher temperature tolerances, free cooling and renewable energy in mind, Krystal said. But much of the country’s existing data centre estate predates the recent run of record-breaking summers.
Retrofitting older facilities is possible, but it requires investment and a willingness by operators to identify weaknesses before they lead to disruption. That creates a divide between newer projects designed with changing climate conditions in mind and legacy sites that may need significant upgrades.
The company highlighted several measures operators are using to improve resilience. These include adding extra cooling headroom so the failure of one unit does not trigger a broader outage, using real-time environmental monitoring, securing resilient renewable-backed energy supplies, and stress-testing facilities against worst-case scenarios rather than historical averages.
Questions for customers
For businesses that rely on third-party hosting providers, climate resilience often depends almost entirely on the operator running the infrastructure, Krystal said. It suggested customers ask where their data is physically located, what flood and heat risks apply to that site, how uptime guarantees are supported, what energy sources are used and whether the provider is transparent about past incidents.
The comments also reflect a wider industry debate over whether traditional measures such as uptime percentages tell customers enough about resilience. Operators may report high availability figures, but those numbers may not show how infrastructure performs during rare but severe weather events.
The issue has become more pressing since the UK classified data centres as part of Critical National Infrastructure. The designation places them alongside sectors such as energy and water in terms of national importance, increasing scrutiny of how prepared operators are for more volatile weather conditions.
Tech industry bodies have also highlighted the risk. techUK has identified heatwaves, temperature variability, water scarcity, flooding and strain on the electricity grid as leading climate threats to UK data centres, underlining that weather resilience has become as much an operational question as an environmental one.
Dave Kimberley, Chief Executive Officer of Krystal, said the sector needs to look beyond headline uptime numbers when assessing resilience. “The majority – if not everybody – in this industry can quote you an uptime percentage to at least two decimal places. But if you ask what temperature range that number caters to, then some won’t be as vocal. And that’s where the real gap is – resilience is so often reported as an average, but when it comes to a drastically changing climate, averages lose their meaning.
“A data centre doesn’t fail on a bad month – it fails on a single extreme day. Until ‘built for extremes’ is the standard data centres are actually built to, businesses are inheriting climate risk without even knowing they’ve taken it on.”

Apprentices say AI is reshaping tech skills demand
Atos highlighted the views of three apprentices entering the technology industry, focusing on apprenticeships as a route into tech as artificial intelligence reshapes workplace skills.
All three work as First Line Service Desk Apprentices and described a jobs market in which technical knowledge alone is not enough. Alongside coding and troubleshooting, they said communication, customer service, problem-solving and adaptability have become central to early careers in IT.
Kyle Brady said he moved into an apprenticeship after studying physics, maths and computer science at A level, then spending time in temporary work, including as a forklift driver, while building his technical skills independently. The apprenticeship, he said, offered a way to gain workplace experience while continuing to learn.
His account points to a common hurdle for new entrants: gaining practical experience before securing a first role. Brady said that challenge shaped his view of what employers value in technology jobs.
“After completing my A levels in physics, maths and computer science, I knew I wanted a career in technology. I’ve always enjoyed solving problems and understanding how things work, but I found it difficult to get my foot in the door. I spent some time in temporary jobs, including as a forklift driver, while building my technical skills in my own time. When the opportunity to start an apprenticeship came along, it felt like the perfect way to gain real workplace experience while continuing to learn.
“One of the biggest things my apprenticeship has taught me is that a career in tech is about much more than technical knowledge. Working on the helpdesk has shown me how important communication, customer service and problem-solving are. Being the first point of contact for users has completely changed how I see the industry and helped me develop skills I never realised I’d need. The experience has also shown me how quickly technology is evolving, especially with AI becoming part of more workplaces. That means the ability to keep learning and adapting is becoming just as important as technical skills. My apprenticeship has helped me build that mindset while giving me hands-on experience with the realities of working in IT.
“It’s also opened up opportunities I wouldn’t have had otherwise. Learning about career paths in cybersecurity and data engineering has shown me the range of opportunities available and given me confidence about where my career could go next. I’d encourage anyone thinking about a career in technology to keep an open mind and not feel like university is the only route. Apprenticeships give you the chance to earn while you learn, develop practical skills from day one and build the confidence to adapt as technology continues to change. In an industry being transformed by AI, that real-world experience is invaluable,” Brady said.
Ryan Cresswell said he studied IT at college and games design at university before working in sales to strengthen his people skills. He later returned to technology, but said employers often wanted practical IT experience as well as qualifications.
His experience reflects a wider issue for people seeking entry-level technology roles. Employers often ask for evidence of workplace readiness even for junior positions, making apprenticeships one way to bridge the gap between education and employment.
“After studying IT at college and games design at university, I began working in sales to hone my people skills before returning to technology. One of the biggest challenges I faced while applying for jobs in tech was that employers liked my qualifications but wanted candidates with hands-on IT experience. That made it difficult to get my foot in the door.
“My apprenticeship has given me the opportunity to earn, learn and gain practical experience at the same time. It’s allowed me to develop my technical troubleshooting skills, but I’ve also learned a lot about communication, problem-solving and handling different types of people. My advice to anyone considering a career in tech is to explore the different paths available. In the past it felt like university was the only choice, but that’s no longer the case. Also, speak to people already working in the industry and stay curious. Apprenticeships are a great way to build skills, confidence and hands-on experience, whether working individually or in a team, while discovering what’s right for you. The most important thing is to keep learning and not be afraid to take a different path if the first one doesn’t work out,” Cresswell said.
Skills shift
Zainab Hussain said she chose an apprenticeship because it offered immediate workplace experience and a path into more senior roles without student debt. She said the role had helped her develop both technical and interpersonal skills, including troubleshooting problems and explaining complex concepts clearly.
Her comments underscore how apprenticeships are being framed by employers and trainees as an alternative to university for some digital roles. In this case, the appeal lies in earning while learning, building professional networks and gaining direct exposure to the daily demands of IT support.
“I’m naturally drawn to tech and have always been IT literate, so I knew it was the right path for me. It’s an industry that’s constantly evolving, and I wanted to be part of that. I chose an apprenticeship because it felt like the best way to gain real experience from day one, and it sets you up to move into higher roles faster than if you go to university. I also wanted to build a career in the industry without taking on student debt.
“My time at Atos so far has helped me develop both my soft and technical skills, such as how to troubleshoot problems and communicate complex concepts clearly. I’ve also had the chance to earn, learn and build my experience, all of which are helping prepare me for the next stage of my career. The apprenticeship path has given me valuable opportunities to network with co-workers from different career backgrounds and skill sets, which you wouldn’t get at uni. The workplace experience has been incredibly valuable, so if you’re interested in tech, I’d encourage you to go for an apprenticeship, explore every opportunity available and keep an open mind,” Hussain said.
Taken together, the three accounts point to a shift in the skills mix associated with junior technology roles. As AI tools become more common in workplaces, the apprentices said the ability to keep learning, work with users and adapt to changing systems is becoming as important as formal technical training.
All three also described apprenticeships as a practical answer to the experience barrier that can prevent candidates entering the sector. They framed the route as a way to gain income, training and exposure to real workplace problems at the same time, while opening paths into areas such as cybersecurity, data engineering and wider IT support.

UK flight school collapsed into liquidation
Liquidators have been instructed to wind down Go Fly Oxford, which provided lessons for commercial and private pilots licences.
Colin Wilson and Emma Mifsud, of Opus Restructuring & Insolvency, have been appointed as joint liquidators for Go Fly Oxford Ltd back in May 2025.
But new records filed by the liquidators have revealed an HMRC secondary preferential claim of £118,132.
Ten unsecured claims have been received by the liquidators totalling £60,314.
Further unsecured creditor claims estimated in the statement of affairs total £88,955, the published documents say.

Over the past year, liquidators say they investigated whether any recoveries could be made from directors or other parties, but concluded there were no further viable assets or claims.
Aircraft shown in the 2024 accounts at a book value of £238,181 had been sold before liquidation. The liquidators found the sales appeared to be at fair value and saw no basis for a claim over the transactions.
The aircraft sales happened about seven months before liquidation, outside the relevant period for a preference claim.
The aircraft were reportedly transferred to creditors and leased back so the company could continue trading.
A purchaser of a PA34-200 aircraft was said to owe £6,000. The liquidators received £4,980; the remaining £1,020 was treated as settled because the purchaser had paid a company liability instead.
Two employees were made redundant on 31 March 2025 and were given information to submit claims to the Redundancy Payments Service.

The flying school was based at Oxford Airport when it collapsed.
Its website, which has since been shut down, described the business: “At Go Fly Oxford we pride ourselves on offering a personal and tailored approach to pilot training.
“We know that people learn at different paces and in different ways, this makes catering for individual needs our main target.”
Oxford Airport’s main trade is pilot training. Flight schools at Oxford train pilots who go on to fly for more than 100 airlines in the UK and globally, including for British Airways.
Historically, the airport has been Europe’s foremost centre for professional pilot training with well over 40,000 students having started their careers there.
At one point, the airport’s runway was the busiest in the world with more than 235,000 movements a year (a take-off or landing) and up to 1,100 flights in a single day, its website says.
The business’ report says: “Over the course of 2025, the company will be complementing its Diamond DA40 fleet with a new fleet of Elixir aircraft, a safer and more efficient type of aircraft, which will provide a much reduced cost per flight hour.
“This, along with growth in enrolments and full utilisation of the European base will ensure the profitability of the business in the coming years.”
