Have you been affected by the widespread outage of Microsoft services worldwide?

A widespread outage affected many Microsoft services on Friday, July 19, causing incidents in thousands of businesses and institutions around the world.

This Friday, July 19, around 2 a.m. French time, many Microsoft services were affected worldwide by a technical incident, whether it was Windows, its Azure cloud service or its Microsoft 365 suite. Some television channels stopped broadcasting, planes were unable to take off and many computer systems around the world displayed the famous blue screen of death (BSOD).

The cause? A faulty update deployed by Crowdstrike, a cybersecurity company with tens of thousands of customers worldwide.

A global outage due to… an update

Crowdstrike provides intrusion and data theft protection services to many companies and institutions. Its solutions are used by IT departments to protect employee data, the cloud, and deploy updates to dozens of client workstations at once.

But an automatic update of a proprietary driver deployed by Crowdstrike simply crashed Windows on tens of thousands of machines, from employee laptops to bank servers, display screens in banks and businesses. Quite simply, this is the most significant incident of its kind in history.
