Why would they include that sentence? Are they trying to imply it is rare for them because it is rare for the industry? Are they saying they are not as good as the industry, so customers should move to other providers? Or are they trying to show they apply the same inattention to their customer communication as they apply to their data backup/recovery practices?
This kind of data loss should simply never happen. It’s one thing to say “it will take us up to 30 days to restore your data because our fast recovery options aren’t working and we have to bring up cold archives”, it’s entirely another to say “your data is gone, tough”.
