Data center Circuit - Out of order ingress packets - WAN and DCI

Hey guys,

So I posted earlier this week about an issue we were having in our DC --> https://www.reddit.com/r/networking/comments/f5k828/inbound_packet_lossooo_packetsdup_acks_to_dc_vm/

We started to capture on our ASR's interface connected to the DCI and saw the packets coming into the DC OOO. A capture on the other end confirmed it didn't happen before hitting the fiber.

The internet and DCI circuits are provided by the DC so they have something in common but have you guys ever experienced anything like this? The DCI is sold as dark fiber so you'd think it wouldn't traverse the same path as the internet circuit.

We are failing over to a Level 3 circuit tonight to help clear things up.
