AOL's chief technology officer has resigned from the company, according to an internal company memorandum.

Maureen Govern oversaw the division that inadvertently released search data of over 500,000 thousand users earlier this month.

In a statement, the company expressed its regrets, characterizing the incident as a screw-up that they were angry and upset about. However the incident drew the ire of privacy advocates, calling for a through investigation by the U.S. Federal Trade Commission.

The online division of Time Warner Inc, said it plans to create a task force to review its current customer information privacy policy.

John McKinley, AOL's former CTO, will take over for Govern until a replacement is found.

AOL declined comment.
