Ever tried to grab a file on Usenet only to find it's gone? Or wondered whether older posts — from a few months or even years back — are still on the server? That comes down to one number: retention. The longer your provider's retention, the further back in time you can still download. This page explains what retention actually is, why it matters, and what to expect from a modern Usenet provider.
What is retention time?
Retention is simply how long a Usenet provider keeps articles (messages and files) available on its servers after they are posted. It is measured in days. A provider with 30 days of retention drops anything older than thirty days off its servers; a provider with 4.000+ days keeps a rolling window of more than eleven years.
If a file has 4.000+ days of retention, that means you can still find and download it more than eleven years after it was originally uploaded. Once a post falls outside the retention window, it's removed to make room for new uploads.
Why does retention matter?
Retention is what turns Usenet from a real-time messaging system into a usable archive. Long retention gives you three concrete advantages:
- Access to a much larger archive. The longer the retention, the deeper you can dig. With XS News' 4.000+ days you have access to millions of articles uploaded years ago — old software, classic media, niche discussions, things you can no longer find anywhere else on the open web.
- No more "file no longer available". Cheap or free Usenet services often only offer a few weeks of retention, which means most NZBs older than a month or two just won't work for you. With long retention, your indexer hits keep working for years.
- More reliable downloads. When a post is kept across many servers for a long time, the probability that all of its parts are still complete is much higher. That translates into fewer failed or partial downloads.
How does retention work in practice?
When you click an NZB or pick an article in your newsreader, the client asks your provider's server for the underlying Usenet articles. If those articles still fall inside the provider's retention window, they're sent to you and your newsreader reassembles the original file. If they don't — if the post is older than the provider's retention — the server returns "article not found" and the download fails.
This is also why two providers can give wildly different results for the same NZB: the file might be inside one provider's retention but outside another's. With a deep-retention provider like XS News, that gap is almost never the limiting factor.
Retention isn't the only thing — but it's close
When you're comparing Usenet providers, retention is one of the few specs that's objectively measurable, but it's not the whole picture. The full short-list:
- Retention — how far back you can still download.
- Completion — what percentage of older articles still arrive in one piece. Long retention is only useful if the articles inside that window are actually complete.
- Speed & connections — your raw download throughput and how many parallel connections the provider allows.
- Encryption — TLS/SSL between you and the server should be standard, not an upgrade.
