AT&T routing problems towards www.worldspan.com?

[sthaug () nethelp no]

We have problems reaching www.worldspan.com (216.113.132.22) from
some locations. The common problem seems to be AT&T (AS 7018). Our
AS path towards the 216.113.128.0/19 prefix is typically

   3356 7018 17228 19631

Anybody else see problems here? I note that I can ping 216.113.132.22
from some locations within our network - but not, for instance, from
route-server.ip.att.net.
