> While we successfully traversed more than 7,000 dark signals on Saturday, the outage created a concentrated spike in these requests. This created a backlog that, in some cases, led to response delays contributing to congestion on already-overwhelmed streets. We established these confirmation protocols out of an abundance of caution during our early deployment, and we are now refining them to match our current scale. While this strategy was effective during smaller outages, we are now implementing fleet-wide updates that provide the Driver with specific power outage context, allowing it to navigate more decisively.

Sounds like it was and you’re not correctly understanding the complexity of running this at scale.

Sounds like their disaster recovery plan was insufficient, intensified traffic jams in already congested areas because of "backlog", and is now being fixed to support the current scale.

The fact this backlog created issues indicates that it's perhaps Waymo that doesn't understand the complexity of running at that scale, because their systems got overwhelmed.
