Interference is the best explanation for intermittent connectivity issues that coincide with heavy machinery operation. Heavy machinery can generate a significant amount of electromagnetic interference, which can disrupt network signals, particularly in wireless networks. This explanation aligns closely with the symptoms described - intermittent issues coinciding with external activity. The other options may cause connectivity problems, but they do not align as closely with the described situation: a broadcast storm would likely cause consistent network slowdowns, not intermittent issues; duplicate IP addresses would cause specific devices to struggle with connectivity, not a general network-wide intermittent issue; and defective SFP modules would likely lead to a consistent loss of connectivity, not an intermittent problem.
