At most places I've worked, we can still get things done when AWS/GCP/Azure/OCI are down. For my own selfhosted work, I'm more self-reliant. But I'm aware there are some companies who do 100% of their work within AWS/GCP/Azure/OCI and are probably 100% down when they go down. That's a consequence of how they decided to architect their apps, services and infrastructure.
