This might be caused by rather strict route filters based on IRR at
AS3320 (DTAG). We also don't see this route via our AS3320 transit.

I see the following pathes:
... 1273 14413 197612
... 1299 14413 197612
... 6939 14413 197612

$ whois -h whois.ra.net AS-LINKEDIN
as-set:         AS-LINKEDIN
...
members:        AS13443
...

Other IPv6 routes of LinkedIn are visible via AS3320:
       2620:109:c006::/48 <neigh> 10         100        0      E     
         AS_PATH: 3320 2914 14413 55163
       2620:109:c00d::/48 <neigh> 10         100        0      E     
         AS_PATH: 3320 2914 14413 20049

Not feeding IRR DB fires back. You might want to ask LinkedIn to fix
their entries.
