What is completion rate and why it matters for Usenet?

The internet as we know it was formally invented in 1983 even though the planning for this global network began decades ago. It began as ARPANET, a research program funded by the U.S. government, and was primarily used in academic settings before it made its way into everyday life. In 1989, a British scientist named Tim Berners-Lee invented the World Wide Web (WWW) system that made it easy to locate resources online and is largely in use today. 

But, before the internet, there was something called Usenet that enabled computers to communicate with each other across long distances. It was invented in 1980 by two graduate students named Tom Truscott and Jim Ellis. This system has largely lost out to the mainstream internet but it still exists today and presents a good way for people to share resources online.

The three most important aspects of Usenet are the newsgroup, news server, and news reader. A newsgroup is a discussion group on Usenet where users can share posts with each other; the posts could be text, photos, videos, audio, or any other file type. The news server is the system that manages the routing and storage of posts on a newsgroup. The newsreader is a program that enables computers to read messages posted to newsgroups. 

Usenet providers 

Usenet providers are the companies operating news servers that let people access newsgroups on the Usenet network. Some are free and others paid, and the paid ones usually offer better service than their counterparts. After selecting a Usenet provider, you’ll also need a Usenet indexer, as in a search engine that lets you find files across different news servers. Just like with providers, some indexers are free to use and some are paid.

You need to watch out for certain factors if you want to pick a Usenet provider, including;


Anything posted to a newsgroup takes up storage space on a provider’s Usenet server. Retention is the specific time frame that Usenet providers store newsgroup posts before they are deleted.

Different Usenet providers can have different retention periods for the same newsgroup. The longer the retention, the greater the number of posts you can access from the provider’s servers. We suggest choosing a provider with retention over 5,300 days, consistent retention across all newsgroups, and that also grows retention day by day for access to the largest and most complete archive, including the oldest and newest posts to Usenet. This will drastically improve your search and completion rates. 

The daily Usenet feed (the number of posts made to Usenet) has increased considerably over the past few years. Users continually post more articles to Usenet every day. Because the size of the files being posted to Usenet is also growing, providers need to continually add more storage space to keep up with user’s posting volume. For the best overall experience, choose a paid premium provider, like Newshosting, that still carries a full historical archive going back over a decade, while also growing retention daily so no posts are expired from its servers.


This refers to how quickly the Usenet server can deliver a requested post to a Usenet user. TechRadar’s best Usenet providers buy premium bandwidth and network access directly from all the large ISPs where you likely receive your internet access from. A direct connection from the Usenet provider’s server to your computer means the fastest and most consistent speeds possible. 

In comparison, some providers purchase cheaper bandwidth from third parties that often have congested connections and slower speeds. ISPs prioritize traffic coming onto their networks, and Usenet providers that buy premium traffic from them will be prioritized ahead of traffic coming through third party networks.

Article size

Usenet providers often place limits on the size of articles they can accept in order to save storage space. Always watch out for this number but have in mind that there are some programs that let you split large files into different articles and recombine them to download on Usenet. 

Completion rate

Completion is the percentage of Usenet articles posted to Usenet that are actually available for users to access on a particular provider’s servers. The higher the completion percentage, the more successful the Usenet experience will be. Different providers have different amounts of retention so, the higher the retention (listed in days) and the higher the completion (listed in percentages) gives a fair estimation of the overall quality of service available from the Usenet provider.

For instance, many Usenet providers advertise a 99%+ completion rate, but be sure to look at the details. Does the Usenet provider clearly state the exact number of days of retention archived? Is the same level of retention available for all binary and text newsgroups, and does retention grow day-by-day? If it’s unclear, it’s likely they are not storing the full Usenet feed and completion will be low no matter what completion percentage is advertised. The best services have high completion rates from large archives of retention. They store all articles posted to Usenet going back over 14 years while also storing all new articles posted to Usenet.


Usenet may not be a hot thing currently, but it’s still relevant. Millions still use Usenet today to communicate on thousands of topics and share digital content like audio and video files globally over the internet. It is an enduring decentralized social media experience with a thriving community and ecosystem of services and features. 

Completion rate is a key factor to consider when choosing a Usenet provider as it determines how many Usenet posts you can actually access from a provider’s servers. Completion rates vary significantly from provider to provider and the advertised completion rates are not always accurate. We recommend using our Best Usenet providers guide to steer you to the services with the best completion rates.
