A power outage at the National Institute of Standards and Technology (NIST) Colorado laboratory caused its atomic clock to go offline, resulting in a 4.8 microsecond latency in the global time standard. This seemingly small time difference could trigger a chain reaction in GPS positioning, telecommunications networks, and other critical infrastructures. From financial transaction settlements to Blockchain network synchronization, precise timing is the invisible support of the modern internet. Once the Timestamp is inaccurate, transaction confirmations and data synchronization may become misaligned. This incident reminds us that invisible infrastructure failures can often impact the reliability of the entire system at the most unexpected moments.
