In 2015, Matt Toback recounted an incident where his team at Litmus faced a global website outage that was initially suspected to be a DNS issue, but was later discovered to be due to an expired domain registration. Despite the critical alert received on a Sunday morning, the team utilized Litmus's Grafana dashboard to monitor performance and availability, which indicated that DNS was functioning correctly, leading them to investigate further. The realization that their domain had expired, due to renewal notices being missed, highlighted the importance of vigilant domain management. This incident underscored the value of Grafana's real-time monitoring capabilities, which allowed the team to quickly diagnose the issue. The experience prompted the consideration of adding features for monitoring expiration times of domains and certificates to prevent similar occurrences in the future. The narrative also served as a promotional message encouraging readers to sign up for early access to Litmus's platform in development, emphasizing the benefits of their visualization and alerting tools.
