document: North American carrier survey : simply the best Network Magazine carried out a North American carrier survey . Thousands of network engineers gave information on providers ' strengths and weaknesses across seven services : private lines , frame relay , ATM , VPNs , dedicated Internet access , Ethernet services , and Web hosting . Respondents also ranked providers on their ability to perform in up to eight categories including customer service , reliability , and price . Users rated more than a dozen providers for each survey . Carriers needed to receive at least 30 votes for inclusion in the survey . Readers were asked to rate carriers on up to nine categories using a scale of 1 -LRB- unacceptable -RRB- to 5 -LRB- excellent -RRB- . Not all categories are equally important . To try and get at these differences , Network Magazine asked readers to assign a weight to each category . The big winners were VPNs
