An availability zone (AZ) in AWS eu-west-2 was flooded by a fire protection system going off within the last year. It absolutely did affect workloads in that AZ. That shouldn't have had a large impact on their customers since AWS promote and make as trivial as is viable multi-AZ architectures.
Put another way: one is guided towards making operational good choices rather than being left to discover them yourself. This is a value proposition of public clouds since it commoditises that specialist knowledge.

What surprised me most about today's fire is that their datacenters have so little physical separation. I expected them to be far enough apart to act as separate availability zones.

Hm, I can't find anything in google about this flooding incident. Can you share some details / source?
AWS may charge more for egress, but that’s not high enough for it to be a concern for most clients.
A bigger, independent concern is probably that there should be sufficient redundancy, backups and such that allows for business continuity. (Note again that I’m not saying that all companies make full use of these features, but those that care for such things do. Additionally, I’ve honestly never heard of an AWS DC burning down. Either it doesn’t happen frequently or it doesn’t have enough of an effect on regular customers, both of situations are equivalent for my case).
Most businesses choose to prioritize the second aspect. Even if they have to pay extra for egress sometimes, it’s just not big enough of a concern as compared to businesses continuity.
