The Night Watchman was a longtime community member who now ran his own Sentry node. Recent alerts needed steady attention, and the node could not depend on a single connection. He scheduled a backup-line test but worried that its noise might obscure an alert requiring action.
He switched the Sentry node to the backup line and watched the alert test for a full hour. An unstable connection made him stop and inspect the cabling; he found a loose patch-cable connector and crimped it tight before watching again. In his test notes, he separated the line switch from the connector fault so a later physical fault would not be mistaken for an on-chain anomaly.
The backup line had passed this round of testing, and the loose connector was fixed. Yet he saw how checking cables while monitoring alerts could make him miss routine messages. Next he planned to make line checks a regular step before a shift and ask another experienced operator how they might cover urgent alerts for each other.
