Cisco ASR 9000: 10gb interface to 4gb provider handoff (Comcast ENS)

I have 3 Cisco ASR 9000 series routers each connected to a 4gb Comcast ENS connection. I have IPSLA probes configured which are showing 10% loss over the Comcast connection, does anyone know of any settings on the interface that should be in place to prevent this packet loss? I have had 3 tickets open with Comcast and they don’t see an issue, any ideas would be greatly appreciated.

Thanks!
