Experts warn it could take ‘weeks’ to fix global IT outage – here’s what we know

While some computers are starting to come back online after yesterday’s massive Windows outage took down many key systems worldwide, there’s still a lot of work to be done. Experts say it could be weeks before things are back to normal.

The collapse was caused by a faulty update to Falcon software deployed in the cloud by a cybersecurity firm called CrowdStrike. Falcon is critical to protecting numerous IT platforms and, most importantly, the Windows operating system. When the bug reached Windows computers, it caused blue screens of death worldwide.
