Inverse: ISPs Improve Net Performance

The Internet posted its strongest performance to date, according to the
latest report released today by Inverse Network Technology, in which the
performance of 25 leading Internet Service Providers was tested.

Inverse’s findings for the fourth quarter 1997 show that ISPs are
continuing to improve their call failure rates, or the amount of times a user encounters busy signals or other logon problems.

The call failure rate dropped from an average of 12.5% in September to 7.9%
in December during peak consumer usage hours of 6:00 p.m. to midnight.
Within a 24-hour time frame, ISP call failure rates dropped from 8.3% in
September to 5.2% in December.

According to Inverse’s measurements, the average time it takes to download
popular consumer Web pages (such as ESPN Sportszone and CNN) was 41.5
seconds in December, a slight decrease from the September rate of 41.8
seconds. Inverse reported Web throughput, including graphics files and Java
applets, averaged 2.03 Kbytes/second, an increase of one percent over the
third quarter.

Inverse also noted that ISPs successfully sent e-mail 95% of the time, and
the messages are received within 5 minutes after being sent. Average upload
speed in December was 7.4 Kbps, compared to 6.9 Kbps in September. Download
rates averaged 6.5 Kbps in December, compared to 5.9 Kbps in September.

As to Internet performance by day of the week, Mondays show the worst call
rate failure, with an average rate of 8.9%, compared to 5.2% throughout the
week. Broken down even further, the worst time of day for call failure
rates is 9:00 to 11:00 p.m. local time.

“Our testing showed that, in general, users experienced a higher level of
Internet performance at the end of 1997 than they did at the beginning of the
year,” said Michael Watters, president and CEO of Inverse Network Technology.

“The Internet became a more reliable place to conduct business by the end of
1997 for two reasons. First, ISPs invested heavily in infrastructure to
improve performance during the year. Second, business customers are demanding and getting service level agreements from ISPs that specify performance and reliability.”

Inverse also introduced today a new ISP rating system that uses such
performance measures as call success rate and throughput. ISPs can receive
grades of A+, A, B, C or D. Those ISPs receiving A+ grades for call failure
rates include and Erol’s, and those rating A+ grades for Web
throughput include Sprint Internet Passport.
