TinyURL, bit.ly and other similar services allow long URLs to be converted to smaller ones on their specific service; the small URL is visited by a consumer and their web browser is redirected to the long URL.

Such services are a ticking timebomb. If they go away, get hacked or sell out millions of links will be lost (see Wikipedia: Link Rot). Archive.org/301Works is acting as an escrow for URL shortener databases, but they rely on URL shorteners to actually give them their databases. Even 301Works founding member bit.ly does not actually share their databases and most other big shorteners don't share theirs either.

Who did this?

You can join us in our IRC channel: #urlteam on EFNet

301Work cooperation

The fine folks at archive.org have provides us with upload permissions to the 301Works archive: http://www.archive.org/details/301utm. They unfortunately do not want to make them downloadable, but the same data is in our torrents too, just in a different format (we use tab-delimited, xz-compressed files while 301works uses comma-delimited uncompressed files).



The easiest way to help with scraping is to run the Warrior and select the URLTeam project. You can also run TinyBack outside the warrior, thought Python 2.6 or newer is required:

 git clone https://github.com/soult/tinyback
 cd tinyback
 # Use ./run.py --help for more information on command-line options
 ./run.py --tracker=http://tracker.tinyarchive.org/v1/ --num-threads=3 --sleep=180
