Only people could view sites or send emails to people using domains in these alternative TLDs. This could be improved through the use of special helper applications, or if a custom configuration was made to their computer, or to their nameservers, or a custom configuration at an ISP upstream in the DNS hierarchy. None of these solutions were as comprehensive as being listed in the default nameservers that are seen when an operating system starts. Whilst technically trivial to set up, actually running a reliable root server network, in the long run, is a serious undertaking, requiring multiple servers to be kept running 24/7 in geographically diverse locations. During the dot-com boom, some alt-root providers believed that there were substantial profits to be made from providing alternative top-level domains. Only a small proportion of ISPs actually use any of the zones served by alt-root operators, generally sticking to the ICANN-specified root servers. This in turn led to the commercial failure of several alternative DNS root providers.
