As recent events have demonstrated, major software outages are an ever-present threat in our increasingly digital world. They may stem from software bugs, cyberattacks, surges in demand, issues with backup processes, network problems, or human errors. Outages can disrupt services, cause financial losses, and damage brand reputations.
