All data on GCS is stored durably (14 9s or something ridiculous like that). The only reason to use dual/multiregion is for lower latency, you're basically paying for geo replication.
Of course, I'm sure many users are not aware of this, and it's not helped by the GCP console defaulting to multi when creating new buckets.

- twistedpair 5y agoDurability is great, but availability is also crucial, unless your business can tolerate hours or more of availability outages. Let's say us-central1 is down for some reason (has happened a number of times), but your customer workloads need to keep running uninterrupted, so you fail over to us-west2. Where should your customer files, that need to be read/written for the customer workloads, be written then? If you kept them all in the region that's on the fritz, you've got upset customers, broken SLAs, etc.
