The route servers operating system, and switches do not use the BGP routes from BIRD, therefore the return traffic goes via static route through IPHouse since they are donating bandwidth to manage the servers/switches externally since the MICE /24 does not exist on the internet.  If they were making changes this afternoon, that could explain it.

My internal monitoring (via SmokePing) shows ping packet loss between 15:20 and 16:10 to the MICE route servers.  As others have mentioned I don't show any BGP or traffic volume issues, and everything looks OK now.    I believe the only change today was adding ports to the Netflix LAG this morning at ~11:15, the last time the MICE route server configuration changed was August 13th.  

Will continue to look for relevant data points...

Just noticed that the utilization graphs were missing data from this afternoon, however not the graphs from the CNS switch, which I assume is on another netblock.

Observing same issues here pinging same route severs from any source netblock in AS16842.
