September 2014 - Submission of new links have been disabled. We plan to keep the old links working for a long time, but we'll see how it goes. It was fun while it was useful, but a URL shortener doesn't serve a real use anymore, so the proportion of "spam to helpful" is all wrong. We posted a notice about this in the summer of 2013, so hopefully not too many people will be surprised! October 2010 - New performance improvements; site is much faster again. The system got a little tired occassionally when thousands of abusive requsts would come in each second. - Various cleanups May 2010 - PHP API example - Internal improvements for abuse handling (APIs, baby!) - Various bugfixes September 24, 2009 - Various bugfixes and performance improvements - Prepare for API upgrade September 7, 2009 - New statistics interface on My Metamark - Removed the last bits of the XML-RPC and SOAP APIs - Update everything to use jQuery - Add link to the Anti-Phishing Working Group from the 'marked as spam' page June 22, 2009 - Enable logins via Twitter, Google, Yahoo, Facebook, AOL and OpenID - Faster load times - More reliably submit the "shorten url" form on enter - Various layout tweaks/bugfixes October, 2008 - Performance optimizations April 13, 2008 - When the long_url is the same, give registered users a unique short url anyway November 2, 2007 - No more SOAP API, sorry! A new and much more extensive JSON/REST based API is coming up. The old REST and XMLRPC APIs continue to work. - New better "My Metamark" page - 50% rewired internals to make future enhancements much easier! May 15, 2007 - We updated the software to put less load on our servers and give you faster responses. Everybody wins! February 13, 2006 - The service was slow or unresponsive for a couple of minutes in the afternoon while we upgraded the internals of the system in preperation for some new features coming soon. July 22, 2005 - User registration via Bitcard. See stats on the URLs you've shortened. - Added TCL API examples, thanks Jordan! April 30, 2004 - Add "extensible urls". You can add extra path information after the short url and it'll get included in the "expanded" url. This also works via the API. For example http://xrl.us/bn redirects to http://askask.com/, so http://xrl.us/bn/notes/ redirects to http://askask.com/notes/ - Check the URL with the SURBL Spam URI Realtime Blocklist before adding it to the database. We should probably run through the database every so often and check old urls. April 2, 2004 - Got the first abuse report (surprised it took that long, sad it didn't take longer), so I added functionality to disable short urls for abuse. March 26, 2004 - Moved to a new server - Many internal changes to prepare for an open source release, including basing the system on Combust. - Add "extensible urls". You can add extra path information after the short url and it'll get included in the "expanded" url. This also works via the API. February 19 2004 - Made the shortening engine not reuse a short url if it has a secret (Thanks Phillip Hallam-Baker!) - Will do the redirect directly without the "landing page" even on the first visit to xrl.us - Made the shortening engine never use L's to avoid confusion with 1's (which have never been used, but anyway ...) November 14 2003 - Added a basic statistics page September 16 2003 - Added Python API examples (Thanks Sopsy!) - Metamark.net domain hijacked. May 21 2003 - More aggressive retries when we check a URL to be added (to be compatible with uber-broken web servers) April 13 2003 - Added PHP API example (Thanks Martin!) March 29 2003 - Strip out commas, dots, etc from the end of the short url when redirecting. March 10 2003 - Compatibility with IMDb. - Change User-Agent string to say XRL/1.00 instead of xrl/0.10. (unrelated to the imdb fix) :-) March 2 2003 - Added helpful "Link to ..." text to the added form. - Removed 'beta' flag from the navigation. January 14 2003 - Added link to the OS X Services Menu service January 13 2003 - Fix compatibility with target.com. Like Amazon they don't always allow HEAD requests, but they do it a bit differently than Amazon. Thanks to Joshua Keroes for the spot. January 12 2003 - Various improvements to the "shorten" bot on irc.perl.org (and other networks). January 11 2003 - Fixed a bug when incoming urls had newlines in them (they are now stripped) - Added script to convert text to use Metamark urls. - Added an expiration policy - Added a lookup method to the APIs. January 7 2003 - Generating all pages dynamically is no excuse for not supporting If-Last-Modified headers. Fixed the site to support them.
