TinyURL is a website that allows long URLs to be converted to smaller ones on their service; the small URL is visited by a consumer and their web browser is redirected to the long URL.

Services like TinyURL are a ticking timebomb. If they go away, get hacked or sell out millions of links will be lost (see Wikipedia: Link Rot). 301Works.org claims to archive shorturls, but so far they have not released a single backup file for download. As always, the Archiveteam is here to help with their Urlteam subcommitee.

Who did this?

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

Tools

  • User:Chronomex wrote his own efficient Perl-based scraper: [1]
  • User:Soult did the same in Ruby
  • The Monkeyshines algorithmic scraper has a tool to efficiently scrape URL shortening services -- see the examples/shorturls directory. It scales efficiently to tens of millions of saved URLs. It uses a read-through cache to prevent re-requesting urls, it allows multiple scrapers to run on different machines while sharing the same lookup cache. You can either feed it a list of bare urls, or have it randomly try either base-36 or base-62 URLs. With it, User:Mrflip gathered about 6M valid URLs pulled from twitter messages so far.

Or just ask!

Here's a template that worked for me at least once. Well, data is pending but the site owner is gung-ho.

Try sending an email to the website owner:

Hello!

I'm working with Jason Scott of textfiles.org and other members of the
Archive Team.

Since the recent scare involving http://tr.im/'s announced (and then
retracted) imminent demise, we've been working to archive all the
links from URL shorteners around the Internet.

If I'm not mistaken, you operate urlx.org.  Would you be so kind as to
share with us a copy of your URL database?  We'll do our best to
preserve this data forever in a useful way.

We are already very far along in scraping links from tr.im, but it's
faster (and friendlier!) to contact site owners asking for a copy of
their data than it is to scrape.

We've got a domain registered, urlte.am, and all links will be
available for redirect in the format:

http://urlx.org.urlte.am/av3

If you could help us, that would be excellent!

Thank you,

URL shorteners
