Sorry, only virtual shrimp sandwiches for now.

If you don't speak a Scandinavian language, you do not have to understand this page.
This page has always been known
as räksmörgås.josefßon.org. Under IDNA2003, that
translate into xn--rksmrgs-5wao1o.josefsson.org.
However with the IDNA2008 standard, introduced much later than
this site (see history below), that name would translate into
xn--rksmrgs-5wao1o.xn--josefon-4va.org which
unfortunately is not possible to register
because .org does not support ß and IDNA2008. Thus,
depending on browser configuration, if you type
räksmörgås.josefßon.org you might not actually end up
here any more. In that case,
try räksmörgås.josefsson.org.
This site went public on 2003-03-22 17:34:34 UTC, about a month after the 'xn--' IDN prefix was announced. Only minutes later was the e-mail address below working. A couple of hours later, this page was linked from the GNU Libidn home page on www.gnu.org. Does that make this the first public site on the Internet using a non-ASCII domain name? Inquiring minds want to know.
On 2012-09-10 this site started using HTTPS with a certificate signed by CACert. See below for certificate information.
On 2016-11-04 it received a HTTPS certificate from Let's
Encrypt which now apparently supports IDNA certificates.
Initially Let's Encrypt did not support this initially, you would get a {"type":"urn:acme:error:malformed","detail":"Error creating new authz :: Internationalized domain names (starting with xn--) not yet supported","status":400} error.
