1. A system comprising:
one or more processors; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
receiving, by a last hop router, an indication that an application executing on an end user device has identified a multicast data flow that is experiencing traffic loss;
monitoring, by the last hop router of the multicast data flow, incoming traffic of the multicast data flow being received at the last hop router from an upstream router of the multicast data flow;
determining, by the last hop router, that an expected amount of the incoming traffic of the multicast data flow is being received at the last hop router from the upstream router; and
at least partly in response to the determining, transmitting, by the last hop router and to a network administrator device, a message indicating a network fault is occurring at a location of the last hop router in the multicast data flow.
