Routing-Probs within BBnPlanet

Hi !

some of our customers complain about really bad routing to 
www.apple.com

As this traceroute shows, the problem can be somewhere at bbnplanet.
Since i don have any account there, i cant see the routing from
bbnplanet to us. I seems to be asymetric routing or something else...
Starting from Hop 13 the times are unacceptable... 

Does anybody have any idea ?

Our AS is 5549, the Source IP is either 194.97.200.30  or 195.254.23.1

The first Net is announces as a /16 from our former upstream, we have

The second block has no super-route, but is splitted between us and another
isp. We have 195.254.0.0/17
