	I sincerely hope you're not crossing the Atlantic to get to
destinations in the Pacific. (c:

	However, that said, this looks normal to me.  Keep in mind that
different providers will have different connectivity and differing 
routing policy; as you cross a provider boundary, the reverse route to
you will change.  Traceroute only shows you half of the picture, you 
need to infer the other half, or collect traceroutes from providers
along the forward path.
