Global IT outage affects Hywel Dda Health Board
A SIGNIFICANT global IT outage caused by a recent software update from cybersecurity firm CrowdStrike has severely disrupted services across various sectors, including healthcare, air travel, and retail. The incident, which began on Friday, 19 July, has affected computers running the Microsoft Windows operating system that use CrowdStrike’s Falcon security product.
Hywel Dda Health Board was affected and acknowledged the technical fault in a message to staff on Friday morning.
The Health Board said that the tech issue was impacting their sites, leading to some staff being unable to log onto the network.
However, they reassured that Office 365 applications such as Teams and Outlook remain unaffected, thus allowing remote work to continue uninterrupted.

Dr Junade Ali, a cybersecurity expert and Fellow at the Institution of Engineering and Technology (IET), commented on the scale of the disruption: “The recent software update from CrowdStrike has resulted in a significant global outage. This issue has led to widespread disruptions, including air travel delays, interruptions in television broadcasting, and halted supermarket transactions. The NHS, which relies heavily on Windows computers, is also experiencing outages in critical systems used by GP practices. The root of the problem seems to be a defective system file included in the update.”
Beth Clarke, a digital expert and Committee Member for the BCS Special Interest Group in Software Testing, emphasized the complexity of the issue and the importance of rigorous software testing: “It’s too early to know what factors led to this defect making it into the update, but the cause is probably more complex than just one single point of failure. Incidents like this highlight the importance of thorough software testing and the critical role that software testers still play in the technology sector.”
The global impact of this outage underscores the increasing dependence on digital services and the critical need for their security and resilience. Professor Ian Corden, Fellow at the IET, reflected on the broader implications: “The major IT outages that are occurring around the world today highlight the ever-increasing dependence of national and regional economies, defence and national security, and private individuals on digital services. The importance of reliably-engineered software and IT systems is now paramount, especially where critical national infrastructure (CNI) is impacted.”
The problematic update to CrowdStrike’s Falcon, an endpoint detection and response (EDR) platform, has led to widespread service interruptions, particularly affecting systems running Microsoft software. Falcon is designed to protect computers and other devices from cyber threats by monitoring systems for intrusions and blocking malicious activities. The software’s high level of privilege allows it to significantly influence computer behaviour, preventing security breaches, but also means that any faults can have far-reaching consequences.
Ian Golding, another digital expert at the IET, highlighted the complexity of maintaining interoperability among various IT providers and systems: “Despite organisations using well-known and carefully chosen global IT providers, they all must work seamlessly together. This interoperability is usually extremely well managed and tested with great skill and diligence, but it is complex, and as we see, this can fail occasionally.”
David Smith, Head of Technology Strategy at the IET, pointed out the inherent risks in cloud services and the necessity for robust business continuity plans: “When cloud services go wrong, a large number of customers are affected. These types of services are updated constantly – a feature of the modern world and how we use technology at a global scale. Organisations should learn from every incident like this to become more resilient to events that affect so many customers around the world.”
As CrowdStrike continues to investigate the incident with the highest level of urgency, the long-term implications of this outage remain to be seen. This incident serves as a critical reminder of the need for meticulous software engineering and comprehensive disaster recovery strategies to mitigate the risks of such widespread disruptions in the future.

Welsh Ambulance Service stands down critical incident after heatwave pressure
THE WELSH AMBULANCE SERVICE has stood down the critical incident declared on 26 June following three days of sustained pressure linked to the extreme heat.
The service said demand has now begun to reduce, although it remains under significant pressure.
Members of the public are still being urged to call 999 only in serious or life-threatening emergencies.
For less urgent health concerns, people are being asked to use NHS 111 Wales or the online Albot service for advice and support.
The Trust thanked staff, volunteers, partner organisations and the public for their patience, professionalism and support during what it described as an exceptionally challenging period.

Welsh Ambulance Service urges public to ‘choose wisely’ as pressures continue
THE WELSH AMBULANCE SERVICE has issued a fresh appeal to the public following the declaration of a critical incident on Friday (June 26), as exceptionally high demand continues to place pressure on crews across Wales.
In a social media post published today (Saturday, June 27), the Trust warned that hot weather is contributing to a rise in ambulance call-outs, including incidents involving heat-related illness, falls, breathing difficulties and existing medical conditions worsened by the heat.
The message comes less than 24 hours after the service declared a critical incident amid unprecedented demand, with ambulance resources stretched across Wales.
The Trust is urging people to call 999 only for serious or life-threatening emergencies, contact NHS 111 Wales for urgent health advice, and use local pharmacies for minor illnesses and ailments.
It said choosing the right service can help ambulance crews reach the sickest patients more quickly while pressures remain high.

Nursing leaders demand urgent action to end corridor care in Welsh hospitals
RCN Wales joins doctors, patient groups and charities in call for national reporting before summer recess
NURSING leaders, doctors, patient groups and charities have called on the Welsh Government to take urgent action to end corridor care in Welsh hospitals.
A joint letter signed by Age Cymru, BMA Cymru Wales, Carers Wales, Llais, Marie Curie Cymru, Royal College of Nursing Wales, Royal College of Emergency Medicine Wales, Royal College of Pharmacy and Royal College of Physicians sets out a series of steps ministers are being urged to take immediately.
The organisations want the Welsh Government to publish a formal definition of corridor care, introduce national reporting, monitor the issue as a patient safety indicator, and require health boards to produce local plans focused on the most vulnerable patients.
They have also called for a coordinated approach across health and social care, warning that the problem cannot be tackled properly unless it is measured consistently across Wales.
The groups want a public commitment from the Welsh Government before the Senedd’s final sitting day before the summer recess on July 17.
‘Unsafe and unacceptable’
Corridor care refers to patients being assessed, treated or cared for in inappropriate areas such as corridors, waiting rooms, ambulance bays or other spaces not designed for clinical care.
Health bodies have repeatedly warned that the practice can put patients at risk, reduce privacy and dignity, and leave staff unable to provide the level of care they know patients need.
RCN Wales Executive Director Nicola Williams said corridor care was still happening every day across most hospitals in Wales.
She said: “Earlier this month, we welcomed the Cabinet Minister for Health and Care’s determination to address corridor care following England’s first publication of corridor care statistics.
“I have also been encouraged by the verbal commitments I have received from Welsh Government officials that echo our priorities of a clear, consistent definition of corridor care across Wales, and the development of a data set for use across NHS Wales for public reporting.
“Corridor care continues to happen every day across most hospitals in Wales, putting patients’ wellbeing and lives at risk and affecting the morale of nursing staff who cannot give the care that patients deserve.
“We must be able to quantify this problem if we are to eliminate it.”
Ms Williams added that the RCN must be involved in efforts to eradicate corridor care because nurses are “at the forefront of this crisis and a vital part of the solution.”
Wales behind England
The call comes after NHS England began publishing national corridor care data, giving a clearer picture of how often patients are being treated in inappropriate settings.
In Wales, there is still no formal national definition of corridor care and no routine public reporting.
RCN Wales has argued that without consistent data by health board, it is impossible to know the true scale of the problem, identify trends or hold the system properly accountable.
The issue has been raised repeatedly by nursing and medical bodies in recent months. In January, RCN Wales published a briefing calling for care delivered to a patient in a chair for more than 24 hours to be treated as a “never event.”
The RCN and BMA Cymru Wales have also called for reductions in hospital beds to be paused, for capacity to be reviewed nationally, and for greater investment in community and social care so patients who are medically fit to leave hospital can be discharged safely.
Healthcare Inspectorate Wales has also warned that corridor care should not become normalised, saying care in non-clinical spaces can compromise patient safety, dignity and the quality of care.
West Wales concerns
The issue is particularly relevant in west Wales, where hospital capacity, ambulance handover delays and the future of local services remain politically sensitive.
Hywel Dda University Health Board has faced repeated criticism over pressures at Withybush, Glangwili, Bronglais and Prince Philip hospitals, with patients in rural areas often facing long journeys for emergency treatment.
The call from nursing and medical bodies comes days after the Senedd backed a motion calling on the Welsh Government to rule out hospital closures and service downgrades during the current Senedd term, with patient safety prioritised.
That debate was dominated by concerns over Withybush Hospital, where changes to emergency general surgery mean some patients who need emergency operations will be transferred to Glangwili Hospital in Carmarthen.
Campaigners argue that distance is itself a patient safety issue in rural Wales, particularly when emergency departments and ambulance services are already under pressure.
Wider NHS pressure
Corridor care is widely seen as a symptom of wider problems across the NHS, including delayed discharges, lack of social care capacity, pressure on emergency departments, workforce shortages and too few available beds.
Doctors and nurses say patients can end up stuck in emergency departments because hospital wards are full, while patients on wards cannot leave because care packages or community support are not available.
The result is a system where pressure builds at the hospital front door, leading to long waits, ambulance queues and patients being cared for in unsuitable spaces.
The Welsh Government has previously said it recognises the seriousness of the issue and is committed to improving urgent and emergency care.
But professional bodies say recognition is no longer enough and that Wales now needs clear national data, local health board plans and public accountability.
The joint letter places fresh pressure on ministers to act before the Senedd breaks for summer.
For patients and staff, the message from Wales’ leading health organisations is blunt: corridor care cannot be ended until Wales properly defines it, measures it and treats it as a major patient safety issue.
