April 12, 2001, 4:45 PM — Here's our latest quarterly report from Network World and Visual Networks as we look at the top ISPs in the market. Through statistical analysis of Visual's Internet BenchMark data for dial-up service (see How We Did It), we ranked the top ISPs in the business-to-business, national and regional ISPs, as they compare to other vendors within the same market. We've also included results for the past six months, to show whether an ISPs ranking this month has spiked or is consistently above average.
In October 2000, AT&T's WorldNet service continued to top the national retail market, performing above the industry average in four out of nine categories tested. The regional retail market continued to be strong, with Ameritech taking the top spot, but with Verizon-North, BellSouth and SBIS close behind. Finally, AT&T's Global Network Service (GNS) took the top position in the business to business market for October, with Concentric and UUNET's GridNet service close behind.
