Yahoo! Lessons Learned

As much as I enjoy finding out about Yahoo & GlobalCenter issues by reading the newswires, I wonder if there are any lessons we can learn from these events. Or was this not big enough to get attention of upper management? Was there something Yahoo!, GlobalCeneter or other providers could have done, either individually or in cooperation, to prevent the problem? Likewise, could they, individually or in cooperation with other providers, have shortened the duration or severity by doing something different? And finally, would they be more successfull in tracking the source the the problem by doing something different?
