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.
