The 109/8 range was removed from our ISP Ingress Prefix Filters in
version 22 (dated 6-Feb-2009):

Hi there,

A customer of mine is reporting that there are a large number of
addresses he can not reach with his addresses in the 109/8 range. This
was declassified as a BOGON and assigned by IANA to RIPE in January

If you have a manually updated BOGON list, can I please ask that you
review it and update it as soon as possible please? His addresses in
89/8 and 83/8 work just fine, hence this presumption of BOGON filtering.
