In the United States, Thanksgiving marks the unofficial start of the holiday season and is a stressful day for many systems engineers as they prepare for Black Friday and Cyber Monday. Uptime is crucial during these events, but even 99.99% uptime can be disastrous if it occurs at the worst moment. The potential fiscal impact of being down an hour is significant, with $417 million lost per minute and $7 million lost per second. To avoid a disaster, developers and SREs must invest in performance testing and API load testing to ensure their systems can handle unpredictable traffic spikes and patterns. Security testing is also essential as hackers will exploit vulnerabilities during outages. Chaos testing or failover testing can help minimize the damage of a potential outage by designing the system to fail predictably. Better planning and synchronicity among QA teams can also prevent disasters, but it's often too late once the issue arises.
