Whether or not you are missing networks probably depends on your
perspective:
route-views.oregon-ix.net>sh ip bgp summ
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd

BBN, ATT, ATT CERFnet, and Sprintlink appear to consider what you
are receiving a full table.
Verio considers 93,000 prefixes to be 10,000 /more/ than a full
table (See Randy's post of a few days ago):
204.42.253.253 4 267 731675 6881 6971912 0 0 1d08h 83878
204.212.44.131 4 234 275728 6913 6971912 0 0 1d08h 83710
In any providers advertisements, there is going to be a certain bit
of fuzz (internal networks, some deaggregates, and other things) that they
advertise to transit customers but are not seen by the world. For example,
downstream customers of, say, UUnet or Telia will easily see more than 100k
prefixes currently, but peers will not see many of those internal routes
and deaggregates.
Telia is currently advertising 100-112k prefixes:
route-views.oregon-ix.net>sh ip bgp summ | incl 1221
203.62.248.4 4 1221 968651 6910 6975582 0 0 1d08h 100315
203.62.252.21 4 1221 807027 6899 6975582 0 0 1d08h 112352
So, it's really a matter of perspective. If you are still having
reachability problems, I'm sure AboveNet would be happy to take a look at
it and fix that for you. If you're just looking for 'missing prefixes,'
I'm not sure that you really are missing anything.
