That might because your traffic dropped i suppose. You can't expect to be always remain on the top position of Google. You will be up and down sometime just like Roller Coaster.
@kimchris I think he meant the reverse? @iamzak Things like that happen all the time, keep at it and you will probably continue to stay there!
