A fire like that in SBG a few days ago is extremely rare. The data lost there compared to all data stored in data centers probably justifies eight 9s. The problem with these numbers is that it's extremely unlikely to lose data but if you do, the event is so severe that everything might be gone. That's why I feel more comfortable storing data across two "unreliable" providers with a lot of physical space in between them rather than one super reliable provider. You also have to consider that data loss can result of simple things such as an account that gets blocked for stupid reasons. If you want to be safe you always need to have your data with at least 2 providers.
