What is Usenet retention? Article retention is the length of time, measured in days, that a Usenet provider keeps an article available to you after it was posted. It’s easy to forget that all internet data has to be physically kept somewhere: despite its name, “the Cloud” exists on servers, not in the sky, and the messages and articles that you see on Usenet have to be held on servers too.
Why Does Article Retention Matter?
Usenet is a massive community wherein users exchange large amounts of information constantly. Providers advertise retention in days to show how far back their article availability extends: the length of time a post stays available on Usenet. Put simply, article retention tells you how far back Usenet reaches for you.
An example makes it concrete: with a provider that offers 365 days of article retention, only articles posted in the last year are available to you; with a provider whose retention runs to many years, you can read a discussion from a decade ago as easily as one from this morning. That is why retention is not only a number of days. Higher retention means more successful searches, because the article you are looking for is still on the network when you look for it, and deeper history within the newsgroups your provider carries, because groups that went quiet years ago are still complete.
Retention is often mentioned together with completion, but they measure different things. Retention is how far back in time a provider’s archive reaches; completion is how much of what was posted is actually available, with no missing parts. A long retention window with poor completion still leaves gaps. Completion has its own page: What is Completion?
History of Article Retention
Article retention was Usenet’s answer to the issue of data storage. Keeping all of Usenet’s archive costs money. Space, energy, cooling, and maintenance all make your data accessible. So, to keep Usenet affordable and accessible, Usenet providers decided to limit the amount of time they would host data. This was the most logical way to ration space on servers. Some providers still use age-based expiration to manage storage capacity: once an article reaches a set age, it expires.
For years that meant posts were somewhat ephemeral: on many early providers an article lasted as little as a month and no more than a year or two. It was efficient, but it cost the network a great deal of its history. As Usenet providers began making deals with ISPs, improved article retention became a major draw at a time when the World Wide Web was still thin and largely non-interactive.
Data Storage
The issue of data storage is largely invisible to the average internet and Usenet user. Some of this is by design. Servers are concentrated in clusters, and keeping them running, with space, energy, cooling and maintenance, is a significant and growing cost. Servers can range in size from Network-Attached Storage devices to massive data centers that have their own independent power and cooling systems. Redundant storage and power guarantees that the hosted data is constantly available at a moment’s notice. Ensuring fast access to posts requested by users is critical. To that end, servers prioritize newer data and more commonly requested data over older data and less commonly requested data.
The problem of data retention is not unique to Usenet, but it is treated a little differently. Google offers 15 GB of space on Google Drive, but extra space costs more. With Usenet, there are no limitations on the size of posts, but on a provider with a fixed retention window an article eventually expires: when it reaches the end of that window, the provider drops it to make room for what is being posted today.
Newshosting Article Retention
On November 1, 2016, Newshosting became the first Usenet provider to reach 3,000 days of article retention. We haven’t looked back since. With each passing day, we add another day to our Usenet archive, and we have no intention of stopping any time soon. In April 2022 Newshosting was likewise the first provider to reach 5,000 days, across all 120,000+ newsgroups. Today Newshosting’s article retention stands at 6636+ days, with 99.99% completion.
What that retention means for you today, and how Newshosting’s archive compares, is on Newshosting’s article retention page.
All in all, article retention is another aspect of Usenet that makes it distinct. We tend to think of storage in terms of the size of articles, so defining storage by a length of time can seem strange to newcomers. With such an active, widespread community, however, Usenet faced unique challenges when it came to data storage. The solution was article retention. Newshosting’s approach altered the landscape of Usenet for good. Now, article retention is constantly expanding, taking Usenet to new heights and preserving all of the great articles from long ago.
