The recent Microsoft outage stemmed from a significant networking issue within the Europe, Middle East, and Africa (EMEA) region. This problem disrupted access to multiple Microsoft 365 services, affecting users primarily in South Africa and the United Kingdom. The services most impacted were Outlook, server connections, and website access. Microsoft identified the problem as a critical fault in the network's routing infrastructure, which caused widespread service interruptions.

How Big
It Is?

CrowdStrike had a market capitalization of approximately $86 billion as of Thursday’s close, positioning it as the second-largest pure-play cybersecurity stock in the U.S. market, with only Palo Alto Networks being larger. Its share price has more than doubled over the past year.

Initially known for its dominance in endpoint security—securing connections between corporate networks and employee devices—CrowdStrike has expanded into cloud security, identity protection, and analytics.

In its latest earnings report, the Texas-based company announced a 33% revenue increase compared to the same period last year, attributing the growth to more companies adopting its cybersecurity platform.
Given that the bug is caused by an update to CrowdStrike Falcon software, chances are that another update should fix it soon. But for now CrowdStrike is offering a manual solution in a note to its customers. It apparently says that to fix the CrowdStrike Windows 10 BSOD issue, the following 4 steps are needed:
  1. Boot Windows into Safe Mode or WRE.
  2. Go to C:\Windows\System32\drivers\CrowdStrike
  3. Locate and delete file matching "C-00000291*.sys"
  4. Boot normally.
