I have a question.

How can the Hotmail server be too busy? Wasn't Microsoft the one that wanted everyone to do their online experience by virtual of their Passport service? How then can the server be 'too busy' when the Passport idea kind of fell apart? Did they sell off all the server space they'd planned to do this service on?

Further to that, how can the Hotmail servers be 'too busy'? Correct me if I'm wrong but isn't there more Hotmail email addresses than there are people on this planet!?! If you know, I mean KNOW, that you are the single largest provider of free email accounts, how then can you allow yourself to fall into a position where your servers are 'too busy'?

I don't get this. I don't understand. Explain it to me like I'm a three year old. How can Hotmail be 'too busy'?
