I'm not sure if you read their entire Mea Culpa, but they did indicate that the root cause of this issue was the provisioning of a legacy filter that they are no longer using. So effectively, that makes it a human error. We're going to a point where a single error is no longer causing outages, something very similar to my favorite analogy: avation. Pretty much every major air disaster was caused by a combination of factors. Pretty much every major outage these days is caused by a combination of factors. The manual provisioning of an inadequate filter, combined with an automation error on the side of a customer (which by itself was probably caused by a combination of factors), caused this issue. We learn from every outage. And instead of radio silence, they fessed up and fixed the issue. Have a look at the ASRS program :) Thanks, Sabri
