Let me try to explain with my limited understanding. Did a lot of research in the past and things change from time to time so some of this might be out of date:
- First, no one knows the exact locations of where the chunks of data are located throughout the system.
- Second, no one knows what the data is.
- Third, when something goes down, it takes a very short time for the network to copy from one of the other existing locations to verify that there is always 4-6 available copies.
Fourth, (this one I’m not sure about anymore) the network tries to keep copies in distant geographic locations. Again, help me out on this one folks in the know. This is to prevent a natural or man made disaster from destroying all the copies at one time.
This is safe and secure in my book.
