Water in the Switchroom

4 min

On a Tuesday night, the overnight supervisor at Ravenscar Telephone Exchange reported that the cable basement had flooded, disabling a bank of trunk-line switches and cutting calls to three villages. The Water Board later confirmed that a rooftop header tank had burst and that an internal pipe in the switching hall had been deliberately diverted — redirecting water away from the overflow drain and toward the cable runs. Three people were on site that night: the supervisor, a visiting repair engineer, and a junior operator. Your task is to reconstruct the exact order of six events — the burst, the diversion, and the flooding, plus what happened before and after — using only the forensic evidence.
