There were zero issues with performance/reliability that caused the outage, they just deleted hundreds of customers data, and had to manually restore the data due to lack of automated restore scripts.
Reliability is measured from a customer's perspective, not from a geeky vendor-oriented perspective of a backend service. When the vendor deletes data, the vendor's reliability quotient decreases, because that data is no longer available to the customer.
Technically 14 days is multi day, but when it can be measured in weeks, you might as well.
