[outages] 81.26.208.0/20 not in BGP table?

Can anyone confirm/deny that this subnet is unreachable? I'm not showing it in my BGP tables from XO or Level(3), and Routeviews also seems to be showing no entries (one entry only, very unusual). I have one report from a customer that it's reachable from Comcast though so I'm looking for some other opinions. -Bill
