You're not used to this from links on the web, but Darknet visitors know it: the page isn't even found. There are two main reasons for this: the site is down or the link is outdated. You can forget almost all link lists before 2021 as the old v2 links are no longer supported since October.
Onion links have been swapped almost everywhere for the newer version v2021 over the course of 3, v2 links are no longer supported by Tor. The v3 links are simply longer, you can find a Tor post about it here. They still consist of tangled character strings, the names of the sites are more or less included in some cases and of course they still only work in the Tor browser.
There are now thousands of link lists on the web that have become largely useless. You will often find a year in the title, unfortunately some update "Colleagues" just the headline... But you can see current lists at a glance, the difference between old and new links cannot be overlooked.
Here is an old and a new address next to each other:
Neu: http://dreadytofatroptsdj6io7l3xptbet6onoyno2yv7jicoxknyazubrad.onion/ Alt: http://xmh57jrzrnw6insl.onion
site is down
However, even current links do not always work. For one thing, there are many sites on the dark web that function more like pop-up stores: they open, run for a while, and then move or just shut down. Just windy Pages can only be found temporarily at one address. Other sites are taken offline by the authorities. Hobbies are not pursued. Data stealing sites have served their purpose. And so forth. This is much more common on the dark web than on the standard internet.
But sometimes pages are just not accessible because they are under heavy load or your Tor connection is bad. This also happens sometimes on the WWW, but super seldom.
Also on Tutonaut.de you will be in the Darknet area tripping over dead links. We're currently updating to v3 links everywhere, but if you still spot v2022 links as of February 2, please let us know in the comments. The same applies to v3 links that are no longer accessible.
