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.

301Work cooperation

The fine folks at archive.org have provided 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 pipe-delimited, xz-compressed files while 301works uses comma-delimited uncompressed files).

Tools

Terror of Tiny Town

The easiest way to help with scraping is to run the Warrior and select the URLTeam 2 project. You can also run ToTT outside the warrior; to do so, follow the instructions at https://github.com/ArchiveTeam/terroroftinytown-client-grab.

Researching URL Shorteners

Here's what to do when you've come across a new URL shortener that should be archived. At minimum, please follow the first step. Anything beyond that is more helpful. Even if you don't know of any shorteners not on the list, additions, updates or verification of the information in existing shortener entries is very welcome!

  • Add it to the Alive section of this page in alphabetical order and include the current date. Please include whatever information you have, but at the absolute minimum, we need the domain.
    • To add a new shortener to the Alive section, you can follow this template:
|-  
| shortener url || date (YYYY-MM-DD)  
| information you have gathered on the shortener  
  • Check the homepage. Is there a public method to create a shorturl? If so, create one and include it in the entry. If not, note that in the entry.
  • If you were able to create a shorturl, try making a second. Is it sequential? For example, if the first link was foo.bar/dbE4g and the second link is foo.bar/dbE4h (or very close to it), it's probably sequential. If you get foo.bar/dbE4g followed by foo.bar/g4rTh, it's probably random. Note in the entry whether the shorturls are random or sequential.
  • Run curl -I http://url.short/validshortcode and see which HTTP status code is returned. Also note whether it returns the destination in the Location: header. Note both in the entry.
  • Run curl -I http://url.short/invalidshortcode and see which HTTP status code is returned. Note that in the entry.
  • If the above fails, make a note of it in the entry and try using curl -i instead of curl -I
  • Check the homepage, and see if they give a total number of shorturls that their service provides. If so, note that in the entry.
  • There are browser plugins/extensions available to make the requests described above from your browser for those without access to curl/command line. (Examples: Advanced REST Client, REST Console)

ushare.education 2016-11-19 The resource-sharing website for Scottish educational resources (run in partnership with the Scottish Qualifications Authority). Not very active, or well known by students / teachers. Resources are shared by a URL, which is shortened. Resources also include a description and rating. All resources can be viewed through the "Search Resources" page, although this likely requires visiting all of the 101 pages in the search results. Each page holds roughly 10 results, so there is probably only around 1000 total URLs, with only a handful being added daily. URLs take the form: http://ushare.education/rsl/<ID>, with ID being an arbitrary non-user-definable string. However the URL shortener seems to have been poorly designed, and http://ushare.education/rsl/null is listed as a link to a resource, yet it does not work. Other links work, and it is currently unknown how many links suffer from this problem - perhaps there is only one. The links on the website are in fact full links to the original resources. This means that it is not necessary even to visit the links to determine their destination - simply parsing the href attribute of the link's tag will do.

tiny-url.info

Seems to provide a centralized place to create shortcodes on multiple services. Provides sample shortlinks for each service, whether provider gives direct forwards, previews, ads or frames. Unfortunately it does not seem to have been updated for several years and the "state" column shows green for services that are down.

Does not allow the creation of new links, current ones work. basically all links are spam links. word-number combinations most likely spam-custom links.

Huge shortener. Long running Project for the future. Hosted on 2 servers at softlayer in Phoenix, Az. Protected by prolexic. Seems like it has not implemented rate-limiting. Tested with 500req in 1 min.

new shortener:
hubs.ly - hubspot.com
robots.txt disallows everyone

Archives

Check out Audit2014 and help audit the archives. In particular, the stuff not on Internet Archive needs to be uploaded.

  • See the latest torrent release for URLs before Tinytown. A copy is available at URLTeamTorrentRelease2013July
  • Tinytown results are uploaded to the Internet Archive. They are incremental, so you will need to download them all to get all URLs. A (manually updated) list of all the torrents is available here.
    • They are formatted as follows:
      • Each IA item (which can be downloaded in full via BitTorrent or as a zip file) contains multiple zip files, named PROJECT_NAME.TIMESTAMP.zip (where PROJECT_NAME is the warrior project name (as listed in the table below, and on http://tracker.archiveteam.org:1337/status) and TIMESTAMP is a dash-separated timestamp matching the name of the item.
      • Each zip file contains a subdirectory matching the PROJECT_NAME, which contains a file named PROJECT_NAME.meta.json.xz and one or more files whose names start with one or more underscores, followed by .txt.xz.
      • The xz files can be decompressed with the wikipedia:XZ Utils.
      • The meta.json file is a copy of the project settings (as linked from the table below) at the time the dump was made.
      • The txt files contain the actual URLs, in BEACON format.
      • The simple description of BEACON format is that each line (except for a few header lines) consists of the shortcode, followed by a vertical bar, followed by the original URL.
