Reaching 3 years-binary retention
There are not many standards which can differentiate a newsgroup provider's offer from another. But one characteristic became more and more important to know if a provider is reliable : days of binary retention.
For several years, newsgroups providers have been tried to increase their binary retention. First they could offer 100 days, then 500 and today the most important providers reached 1095 days, which means 3 years!
Why does it matter? A 3-years binary retention means that you can access to files present for 3 years in the platform, you have thus many more choices.
Those who achieved this exploit are not many yet:
with 1107 days: Giganews
with 1097 days: Usenetserver, Newshosting, Supernews, Powerusenet, Usenet.net, Thundernews, Newsdemon
with 1094 days: Astraweb
