This more specific is only visible via AS3356 ... Facebook isn’t even announcing it via direct peering.
This specific, and many others, are only announced to peers in the metro they originate in. To receive this prefix directly you'll need to peer with us in Los Angeles. It appears you're in Austria though, which means there's likely no use in you peering with us in LA. We globally load balance people to the best point of presence. You shouldn't see much, if any, traffic to or from the above prefix.
Any Facebook admin on or off list available to get this debugged and tracked down?
Please reach out to noc@fb.com in the future. Regards, -- dsp
