In December I posted a story of a Japanese bank employee who made a typo that resulted in $223 million of stock being accidentally sold. Today I’ve got a story from Indiana where an Indiana home was accidentally valued at $400 million. When the correct value was discovered it created an $8 million projected tax revenue shortfall.

Here is where the story gets wierd:

Lippens said the outside user changed the property value, most likely while trying to access another program while using the county’s enhanced access system, which charges users a fee for access to public records that are not otherwise available on the Internet. Lippens said the user probably tried to access a real estate record display by pressing RED, but accidentally typed RER, which brought up an assessment program written in 1995. The program is no longer in use, and technology officials did not know it could be accessed.

30 years from now, how many websites will have programs that their owners aren’t aware that they exist?
