Early Friday morning, the world woke up to major outages across critical systems that rely on Microsoft Windows. These outages appear to be caused by a defect deployed to Windows hosts by CrowdStrike, a technology company that provides security software. Note that the issue is not a security flaw or a cyber attack, but does cause Windows machines to crash and has had serious impacts to airlines, communication systems, Microsoft 365 applications, hospitals, and a host of other critical systems.
RunSignup and TicketSignup are NOT impacted by this outage. Our systems run on the Linux operating system and we do not use CrowdStrike to protect our infrastructure.
