Then there is the issue of having successful connectivity but miserable throughput. The throughput is what we need stats on. A website that I visit often hangs off a GigE switch on the hosting center. Traceroute shows 761 ms through the last hop which is the GigE switch. But pings succeed most of the time. Most SLAs that I have seen so far check for connectivity from usually a NOC to the customer, there is no mention of throughput anywhere.

I wonder if I'm sensitized to Internet problems in comparison to other industries. I checked a couple of other industries often given as examples of high uptimes, and found similar problems.
Ameritech will compensate 150,000 customers who waited more than 48 hours for a repair, or more than 7 days past the installation due date since January 1 2000. Ameritech is under investigation in four other states for missed dates and repair problems.
An e-merchant reports credit card fraud verification system nonfunctional 22 percent of the time. Mastercard and Visa didn't reply to press inquiries.
NASDAQ reports 99.96% system availability since January 1 2000.
AT&T, the only ISP I know publicly posting connection stats, reports 99% connect success last month.
