The OpenNet Initiative ran a series of tests related to Internet access during the recent elections in Nigeria.  Though the election was fraught with issues generally, and though certain web sites were inaccessible during key moments of the election period, we found no evidence of tampering with the Internet.  We’re in the process of refining our election monitoring capabilities, led by Rafal Rohozinski.  We’ve posted a slightly more in-depth statement on the ONI blog.
