United States: Global IT outage has caused by CrowdStrike update leaves a lasting impact on various sectors. The disruption was triggered by a faulty software update from U.S. cybersecurity company CrowdStrike, affecting up to 8.5 million computers running Microsoft systems worldwide, causing widespread disruption.
Healthcare chaos and delays in cancer treatment
In the UK, the IT failure hit the National Health Service (NHS) difficulty, with many General Practitioners (GPs) unable to access the EMIS system, which manages patient records, appointments, and prescriptions. Dr. David Wrigley, a GP with over two decades of experience, explained that the disruption makes the situation worse in critical tasks such as writing referral letters for suspected cancer patients. In some cases, these delays lasted up to four days.
Dr. David told that, “It was a very difficult period with limited help and support.” He described the backlog caused by the system failure. In Surrey, 50 radiotherapy patients had to shuffle their treatments, although the NHS Royal Surrey Trust admitted urgent cases within 24 hours.
Nationwide disruption in Northern Ireland
There were similar problems encountered in Northern Ireland, where about 75% of GPs rely on the EMIS system. Dr. Frances O’Hagan, chair of the BMA’s Northern Ireland GP committee, highlighted that, “We couldn’t do anything for most people. We just had to take it on the chin.”
Both the British Medical Association (BMA) and the Royal College of GPs have supported preventing similar disasters in the future. NHS England and the Department of Health are reportedly working with external suppliers to ensure continuity in case of future outages.
Global travel disarray
The IT disruption has also impacted air travel, with thousands of flights cancelled globally. In the U.S., Delta Airlines was particularly difficult, cancelling around 7,000 flights over five days. The airline now faces legal action and a federal investigation.
In Europe, British travellers were left stranded. Melanie and Alan Cree from Northern Ireland were stuck in Corfu for days after their flight home was cancelled. Laura and Malcolm Jones, on holiday in Rhodes with their children, faced 16 hours of uncertainty before being shifted to a sleeping area. Both families eventually made it home after significant delays, but their travel plans were in disarray.
Small businesses suffers
The outage also had a hurtful effect on small businesses. Dawn Watts, who runs an online supply company in the UK, estimates she lost 800.52$(600£) in sales during the outage.
CrowdStrike faces congressional inspection
Adam Meyers, a senior manager at CrowdStrike, insisted on testifying before the U.S. Congress to investigate the root cause of the issue and outline how the company plans to prevent such concerns in the future. CrowdStrike has expressed regret, with a spokesperson acknowledging the gravity of the situation and committing to learning from the incident to improve service and security going forward.
As investigations continue, the fallout from this outage serves as a notable reminder of the vulnerability of global digital infrastructure to single points of failure.
