In production, nothing ever fails "out of the blue."
The database locked up. The server crashed. The API timed out. The team shrugs and says, "We got unlucky. It just happened out of the blue."
That is a lie.
According to the laws of physics, nothing happens until something moves.
There is always a strict cause-and-effect trajectory, whether you see it coming or not.
The database didn't just lock; a massive analytical query was scheduled at the wrong time. The API didn't just fail; a downstream microservice hit a connection limit, and you didn't configure a circuit breaker.
When an outage seems like magic, it doesn't mean you have bad luck. It means you have bad observability.
Computers do not do magic. They do exactly what we tell them to do.
Stop blaming the system. Start tracing the cause.
