IT team started diagnosing this problem by turning off network segment /switches to isolate the source of the problem which led to re-calculating the routes. These calculations were so complex that those switches gave up doing everything else and network collapsed. Switches were turned on so that the network was back up.

Caregroup IT team was able to find out the root cause of the issue which triggered when a researcher tested an application based on file sharing which copies information across the network which quickly monopolized the entire network slowing down all network traffic due to spanning tree protocol loops.
