On September 15th we reported that Live.com Is Not Passing Referer Information, then on September 18th we reported that MSN Says Live.com Referral Bug "Not By Design". Today I am happy to report that Microsoft has fixed the referral error, and is now passing referer data.

The fix went out a few hours ago, and it's nice to see that it appears to work. We do know this information is important to webmasters, and we regret the inconvenience.
