Don't measure this with ping.. measure it with tcp packet loss. TCP backoff means tcp loses a lot less as its random loss rather than congestion it gets blatted with - and yes many backbones are now badly overloaded. Especially if you are unfortunate enough to share a 64K link with a solaris 2.4 or 2.5 box.
