First of al: since not only tech people but also random users have been disturbed, it IS as major incident. When users lose confidence in computer and softwares, it can be years before they can fully trust it once more.
Second: event if it is only a one day disturbance for customers, since logicitics, administrations, theme parks, banks, hospitals have postponed things and must recover all the computers MANUALLY, it is a complete disaster for confidence in the product. For some, the impact is nearly the SAME as a very bad virus, nearly a ransomware.
It cold have been forgiven for a small company. Here, I really think CrowdStrike CEO must resign. And the company can be brought to its knees. This kind of outage, from a security company that should consider availability and uptime as the biggest ressourceto preserve, and since those products are an incovenience everyday, CrowStrike deserves to disappear... They don't have the right mind to run that kind of business.
