Determining a condition of network communication between servers by detecting changes in sub-user data

A computer-implemented system for determining a condition of network communication between servers, comprising:

• a plurality of sub-user computing devices;
• a user server electronically connected to the plurality of sub-user devices, the user server operative to sense sub-user data of sub-users through the sub-user devices;
• a platform server electronically connected to the user server, the platform server configured to:
• receive the sub-user data over a period of time;
• determine sub-user parameters including a mean, and a standard deviation of the sub-user data;
• determine a modified noise factor based on a value of the sub-user data to make change detection more sensitive to certain values;
• calculate a value of deviation from expectation based at least on the mean, the standard deviation, and the modified noise factor;
• calculate a current cumulative sum value of the user data based on a prior cumulative sum value and the value of the deviation from expectation;
• compare the current cumulative sum value with a preselected threshold;
• detect the condition of the state of communication between the user server and the platform server when the current cumulative sum value satisfies a compared condition with the preselected threshold;
• and
• feed the condition of the state of communication back to the user server when the condition is detected.
