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
