What is a potential sign of Hi Site issues?

The correct answer highlights that a green dot not being green can indicate potential issues with Hi Site operations. The green dot is typically used as a visual indicator in monitoring systems to represent that all systems are functioning properly. When this indicator is not green, it often suggests that there is a malfunction or an issue that may require attention, signaling a possible breakdown in communication or other critical systems.

In the context of maritime operations, algorithms rely heavily on reliable data inputs, and a deviation from expected indicators, such as the color of the dot, can warrant further investigation to ensure that all navigational aids and communication systems are operational. This is crucial for maintaining safety and efficiency during maritime activities.

Other choices provided, while they might imply unusual conditions, do not directly correlate with the types of alerts or indicators specifically associated with Hi Site operations. For instance, a sudden temperature drop might suggest environmental changes, calm weather conditions could indicate a stable environment but not directly relate to Hi Site functions, and increased radio activity, while it may denote operational changes, is not a clear direct sign of Hi Site operational issues as it can vary due to several external factors.
