Facebook more specific via Level3 ?

Tue Mar 21 16:56:29 UTC 2017

Hi,

is anyone else receiving Facebook’s /24 more specific from Level3 (AS3356)?

31.13.70.0/24      *[BGP/170] 1w5d 17:21:28, MED 0, localpref 100, from
a.b.c.d

                      AS path: 3356 32934 I, validation-state: unverified

This more specific is only visible via AS3356 
 Facebook isn’t even
announcing it via direct peering.

Any Facebook admin on or off list available to get this debugged and tracked
down?

Thanks & best regards

Jürgen
