Yesterday, July 22nd 2006, Yahoo! experienced an outage which caused intermittent login issues for Yahoo! Messenger, Yahoo! Voice, and some Yahoo! Mail users. While it wasn檛 an issue to login to Yahoo! Answers and ask about the outage, some Yahoo! sites/products were affected. This issue is now resolved and you can now login.
