IRC channel #urlteam (on hackint)

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.

Tools

  • TinyBack (written in ruby by User:Soult)
  • User:Chronomex wrote his own Perl-based scraper: [1]
  • 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

New table

The new table includes shorteners we have already started to scrape.

Name Est. number of shorturls Scraping done by Status Comments
TinyURL 1000000000 User:Soult 5-letter codes done, on halt due to being banned (2010-12-20) non-sequential, bans IP for requesting too many non-existing shorturls
bit.ly 4000000000 User:Soult lots and lots of scraping needed (2011-03-25) non-sequential
goo.gl ?? User:Scumola started (2011-03-04) goo.gl throttles pulls
is.gd 534183259 User:Chronomex/User:Soult probably got about 95% before switch to non-sequential now non-sequential, new software version added crappy rate limiting
ff.im ? User:Chronomex only used by FriendFeed, no interface to shorten new URLs
4url.cc 1279 (2009-08-14)[1] User:Chronomex done (2009-08-14) dead (2011-02-15)

go.to 60000 User:Asiekierka Done: ~45000 (go.to network links only: goto_dump.zip) no codes, only names, google-fu only gives the first 1000 results for each, thankfully most domains have less
