Password-cracking software

A discussion thread at Reddit today reminds readers to use secure passwords, and offers a link to a password-cracking site called WPA Cracker -
WPA Cracker gives you access to a 400CPU cluster that will run your network capture against a 135 million word dictionary created specifically for WPA passwords. While this job would take over 5 days on a contemporary dual-core PC, on our cluster it takes an average of 20 minutes, for only $17.

NEW :: We now offer Germany dictionary support, a 284 million word extended English dictionary option, and ZIP file cracking.
What I don't understand regarding the susceptibility of sites to password hackers is why a site will permit hundreds, much less millions, of login attempts.  It seems to me that after a half-dozen failed attempts, the bank/broker/retailer or whatever should automatically block further access for some defined time period.

How does a program manage to try ten million access codes?
