"If a company relies on providing a service to millions of customers from a single data centre, with no separate back-up site with its own individually tested architecture, it could face difficult questions."

This is key if you ask me. Making Blackberry reliant on a backend system for any internet usage (Browser, BBM, etc.) without a fallback isn't smart. Letting the service/system then be offline for serveral days...

I'm guessing one of the problems now is that everyone BlackBerry is retrying often, and when it does come online there'll be a huge backlog to handle, meaning more capacity is needed all round.

Despite the fact that it's really pissing me off, it would take a lot worse to get me to switch from BlackBerry. Sadly I don't think that will be the case for a lot of people, and this couldn't have come at a much worse time for RIM.

Ohh blackberry, my lovely 9000 bold is standing in the drawer for 6 months already because i use my android, wish at least you succeeded in the enterprise game; such downtime really came in bad times.

My work Blackberry is still down in Uganda. Pretty brutal.
