There are multiple devices there handling intra and inter-pop traffic. 
NOC still investigating with vendor. 

Redundancy won't kick in if soft or silent failures occur and 
the control plane keeps protocols up but forwarding is affected.
Unfortunately these types of failures still happen from time to
time especially with multi-member LAG groups.

No details on this specific event however.
