In this particular case, they seem to be doing two things: - Phasing out the old proxy (Lua based) which is replaced by FL2 (Rust based, the one that caused the previous incident) - Reacting to an actively exploited vulnerability in React by deploying WAF rules - and they're doing them in a relatively careful way (test rules) to avoid fuckups, which caused this unknown state, which triggered the issue
That's not deserving of sympathy.
