 businesses, banks, and even hospitals around the world. The outage was caused by a cybersecurity update from a company called CrowdStrike, which then impacted Microsoft Windows users and Microsoft's cloud services. CrowdStrike says that it has rolled out a fix for the issue, but the outage has forced the cancellations of hundreds of flights here in the United States and thousands across the globe. It's also forced several major hospitals to postpone surgeries or doctor's appointments.
