On 21:35 eastern standard time, I attempted to execute a search with bing, but I could not. Why? The host www.bing.com could not resolve. For every minute after that until 22:15 I saw the same error as seen in this post. Many other folks I know online could not reach bing either for this time. It returned to service without any explanation. The issue was present on many different operating systems and web browsers.
This yet another reason why Microsoft can not compete in the software-as-a-service market. Will we bing on June 30, 2011? I bet not.
Update: BBC reported that the outage was only 30 minutes due to a configuration change gone bad.
Update2: There was a story on the bing blog the morning afterward concerning the outage. Thank you Microsoft for approving my comment.
