    Strange routing. This is the outbound MTR from my SeFlow server in Milan to CityNet In Cairo

    SeFlow to CityNet

    The MTR from my VPS at Prometeus, another host who is also in Milan, and which also peers with Level 3, takes the same route to Cairo

    Prometeus to CityNet

    The problem is actually CityNet's lack of peering/bad network not anything to do with SeFlow. CityNet is single homed to AS20928 Noor Advanced Technologies which has 3 international peers, 1 of which is the FLAG-TELECO you see in the traceroute. In simple terms, The route has to loop around to where Level 3 and FLAG-TELECO meet up.
