Understanding the Implications of the CrowdStrike Outage
One of the biggest IT outage in history occurred on 19 July, 2024. The largest IT outage was triggered by a substandard software update from security vendor CrowdStrike, affecting billions of Windows Systems across the globe. It is also estimated by the insurers that the outage will cost Fortune 500 companies £4.43 billion.
CrowdStrike is the company at the center of the outage. It is an endpoint security vendor whose primary technology is the CrowdStrike Falcon sensor platform, which assists in protecting systems against any potential threats in a bid to minimise cyber security risks.
In this article, we will understand the severe global ramifications that was caused by the outage of CrowdStrike falcon sensor.
Impact On Education
While some schools reported minor disruptions to internally managed systems, others experienced issues with 3rd party application and online services essential for educational and administrative operations.
In the United Kingdoms, the timing of the outage coincided with the beginning of summer holidays for numerous schools, adding to the complexity. Issues faced by the schools included disruptions in processing school admissions and the functionality of the computer services in libraries, which are mostly used by the students for educational purposes.
Impact On Healthcare
The health sector was not spared from the fallout. Both small medical facilities and larger hospitals faced significant disruptions in their system not allowing them to access patient records, provide timely care, and communicate internally.
Due to this threat intelligence feeds outage, some hospitals even encountered disturbance with phone lines and scheduling systems, leading to delays in patient treatment and appointments. The outage also posed substandard risks for patient’s sensitive data, making it vulnerable to potential cyber threats during the downtime.
Impact On Travel
The CrowdStrike falcon sensor outage wreaked a havoc on the travel industry. Travel airlines worldwide experienced system failures, grounding flights and causing widespread delays and cancellations. Passengers found themselves unable to access flight information, check in, or even manage their bookings.
Airports struggled to maintain operational systems and communication, creating the travel chaos. This incident underscored the heavy reliance of the travel industry on digital systems and highlighted the crucial need for reliable cyber security measures to prevent such widespread disruptions.
Impact On Banking
The banking industry also suffered immensely due to the outage. Banks experienced system crashes that caused disruption in the online banking services, rendered ATMs offline, and halted transactions. Financial institutions were not able to process payments and maintain routine operation, creating frustration among clients and potential financial losses.

Insurance claims are also expected to surge as companies look to cover financial losses, operational downtime, and potential legal liabilities.
Furthermore, for organisations operating with extensive global operations faced considerable costs for manual remediation. This global event serves as a stark reminder of the economic weaknesses posed by cyber security failures and the imperative for difficult protective measures.
Final Thoughts
The CrowdStrike outage was a wake-up call for industries globally, highlighting the crucial importance of IT in our growing digital landscape. From delayed flights and disrupted healthcare services to banking disruptions and broader economic impacts, the incident portrayed the far-reaching influence of cyber security services, and the essential importance of quality checks. As we move ahead, it is crucial for companies to review their cyber security policies and strategies to protect their operations and protect against future disruptions.
