Thank you, unfortunately I and 95% of my customers are in Canada, and
www.webperf.net does not cover Canada (I wish it did).

It wasn't that I thought ping was good, it was a question of tools
available. With my current upstream ISP (PSInet), traffic tops out at
below top speed (64k) during peak internet periods, according to my SMTP
monitor, mrtg (I've accounted for known mrtg problems). I would guess
that this is a problem with the bandwidth of my upstream ISP, not my
bandwidth to the ISP.

It seems like a reasonable idea to try to evaluate a backbone ISP from a
traffic speed perspective, from a random sample of my customers (94% of
whom have dedicated, high-speed connections) to the nearest hub of the
ISP. I need no services from the ISP other than basic throughput, my web
server to customer.

After spending a considerable amount of time at this, I've found the
decision generally seems to be made on a hunch. Large sites have
redundant service from two or more backbones, but I am not near that

So, logic be damned, I guess it's time to flip a coin.

I do appreciate the suggestions.
