CDN routes broken on Optus-peered ISPs in Australia

    Question

  • Our ISP has advised us that 12-20 hours ago, Optus (via BGP) was told not to advertise routes to Azure CDN (Verizon EdgeCast AS15133) to peers.

    This means Uecomm is unable to see a route to our cdn endpoint (which resolves to cs9.wpc.v0cdn.net [117.18.232.200]).

    AS 15133 has a direct peer with Uecomm's peer Optus AS7474 but AS 15133 (117.18.232.0/24) prefer Vocus as their internet peer (do not advertise out to Optus). Vocus AS 4826 has routes towards 117.18.232.0/24 and they advertise to Uecomms peers (Optus), advising them not to advertise (Communities: no-export) to any other peers. Due to that reason Uecomm is not  receiving routes towards 117.18.232.0/24. 

    Uecomm don’t have any control over AS 15133 and 117.18.232.0/24 IP range and how they control their internet traffic. 

    MS azure should have control for the IP 117.18.232.0/24 owned by AS 15133.

  • Hello Jake,

    We have responded to your inquiry via our ticketing system.  Please look for an email from Verizon in your inbox and we can follow through from there.  The upshot is that we announce 117.18.232.0/24 both through Vocus and Optus.  So Uecomm customers should be able to reach either. Please see the email for more details and action plan
