A system to distinguish internal network routing issues within a user plane function (UPF) from external routing issues via multi-domain system (DNS) servers probing is disclosed. The system determines latency in communication between a given UPF and each of a plurality of DNS servers. The system compares each latency with a threshold latency value. If it is determined that each of the latencies in communication between the UPF and each DNS server is more than the threshold latency values, the system may determine that there is an internal network routing issue at the UPF that caused the high latencies. If it is determined that a latency in communication between the UPF and a particular DNS server is more than the threshold latency value, the system may determine that the latency is caused by a network routing issue at the particular DNS server—which is external to the UPF.
