That's because you're using the wrong protocol. Try https in the browser to see their website.

Oh, it seems to rickroll people with a referrer from this site :)

Copy-paste or manually type the URL to get around that!

Edit: They seem to be redirecting with a 301 permanent HTTP response, which seems slightly obnoxious since your browser might cache it. I can't visit the site anymore from the browser I'm using here, so maybe try a different one or incognito mode.

Why would I do that? I'm looking for ssh toys, like ssh starwarstel.net or ssh funky.nondeterministic.computer.
