Re: Bad days happen to everyone
If we consider how much of the internet uses these services and how infrequent these events are, despite the attention each one gets, you could come to the conclusion that the services are actually pretty good at keeping sufficient resilience such that you don't have to worry about them most of the time. I don't know if that's a positive or a negative though--if they were less resilient, then maybe people would have more than one and they could better withstand the failure of one such system.
