What about: WAF cpu usage wasn't isolated from the ability to serve requests? This would allow requests that don't go throwugh WAF to be able to proceed as usual.

A firewall that fails open sounds like a terrible plan.

As far as problems go, an outage is preferable to a breach.

I believe WAF is a feature customers enable, not all customers have it enabled. So some customers are already open, and in theory wouldn't need to be affected by a WAF outage.
