ISPs, news servers, and newsfeeds

Internet service providers, and many other Internet sites, operate news servers for their users to access. ISPs that do not operate their own servers directly will often offer their users an account from another provider that specifically operates newsfeeds. Most commonly, these accounts are through UsenetServer.com, Supernews, Giganews and Usenet.com. Usually the ISP will get a kickback for referring the customer to the Usenet provider. In early news implementations, the server and newsreader were a single program suite, running on the same system. Today, one uses separate newsreader client software, a program that resembles an email client but accesses Usenet servers instead.

Not all ISPs run news servers. A news server is one of the most difficult Internet services to administer well because of the large amount of data involved, small customer base (compared to mainstream Internet services such as email and web access), and a disproportionately high volume of customer support incidents (frequently complaining of missing news articles that are not the ISP's fault). Some ISPs outsource news operation to specialist sites, which will usually appear to a user as though the ISP ran the server itself. Many sites carry a restricted newsfeed, with a limited number of newsgroups. Commonly omitted from such a newsfeed are foreign-language newsgroups and the alt.binaries hierarchy which largely carries software, music, videos and images, and accounts for over 99 percent of article data.

For those who have access to the Internet, but do not have access to a news server, Google Groups allows reading and posting of text news groups via the World Wide Web. Though this or other "news-to-Web gateways" are not always as easy to use as specialized newsreader software, especially when threads get long, they are often much easier to search. Users who lack access to an ISP news server can use Google Groups to access the alt.free.newsservers newsgroup, which has information about open news servers.

There are also Usenet providers that specialize in offering service to users whose ISPs do not carry news, or that carry a restricted feed. One list of such providers is available at UsenetProviders' list of Usenet providers (Germany) or Jeremy Nixon's list of (paid) Usenet providers.
