Software code change reversal tool

A method comprising:

• determining, by a hardware processor communicatively coupled to a memory, that a first hardware server is communicatively coupled to a first network hardware component and a second hardware server;
• generating, by the hardware processor, a graph comprising a first node representing the first hardware server, a second node representing the first network hardware component, a third node representing the second hardware server, a first link between the first node and the second node, and a second link between the first node and the third node;
• determining, by the hardware processor, that the second hardware server is communicatively coupled to a second network hardware component and a third network hardware component;
• adding, by the hardware processor and to the graph, a fourth node representing the second network hardware component, a fifth node representing the third network hardware component, a third link between the third node and the fourth node, and a fourth link between the third node and the fifth node;
• assigning, by the hardware processor, an initial weight to the first, second, third, and fourth links;
• receiving, by the hardware processor, a first change request indicating that a change to the second network hardware component impacted the second hardware server;
• in response to the first change request, reducing, by the hardware processor, the initial weight of the third link;
• receiving, by the hardware processor, a second change request indicating that a change to the third network hardware component impacted the second hardware server;
• in response to the second change request, reducing, by the hardware processor, the initial weight of the fourth link;
• determining, by the hardware processor, that the first network hardware component is malfunctioning;
• and
• determining that the change to the second network hardware component caused the first network component to malfunction based at least in part upon a comparison of a first sum of the initial weight of the first link, the initial weight of the second link, and the reduced initial weight of the third link, and a second sum of the initial weight of the first link, the initial weight of the second link, and the reduced initial weight of the fourth link.

A system comprising:

• a first hardware server;
• a second hardware server;
• a first network hardware component;
• a second network hardware component;
• a third network hardware component;
• and
• a code reversal tool comprising a hardware processor communicatively coupled to a memory, the hardware processor configured to:
• determine that the first hardware server is communicatively coupled to the first network hardware component and the second hardware server;
• generate a graph comprising a first node representing the first hardware server, a second node representing the first network hardware component, a third node representing the second hardware server, a first link between the first node and the second node, and a second link between the first node and the third node;
• determine that the second hardware server is communicatively coupled to the second network hardware component and the third network hardware component;
• add, to the graph, a fourth node representing the second network hardware component, a fifth node representing the third network hardware component, a third link between the third node and the fourth node, and a fourth link between the third node and the fifth node;
• assign an initial weight to the first, second, third, and fourth links;
• receive a first change request indicating that a change to the second network hardware component impacted the second hardware server;
• in response to the first change request, reduce the initial weight of the third link;
• receive a second change request indicating that a change to the third network hardware component impacted the second hardware server;
• in response to the second change request, reduce the initial weight of the fourth link;
• determine that the first network hardware component is malfunctioning;
• and
• determine that the change to the second network hardware component caused the first network component to malfunction based at least in part upon a comparison of a first sum of the initial weight of the first link, the initial weight of the second link, and the reduced initial weight of the third link, and a second sum of the initial weight of the first link, the initial weight of the second link, and the reduced initial weight of the fourth link.
