The graph shows the sharp rise in tech failures from just 3 in the 1960s to over 80 already in the 2020s.
*2020s data includes only incidents up to mid-2025.
The timeline is based on a collected dataset of 184 major failures recorded globally. Selected for their large-scale impact on users, infrastructure, or financial systems, these cases offer a representative view of the most significant outages across decades.
