" because the crash is in the underlying storage the MultiAZ setting makes no difference."

@OP - I don't understand this line... can you explain more?

Aurora read replicas are just compute heads decoupled from the storage. They increase availability and read performance, but don't do anything for the reliability of the storage.

https://aws.amazon.com/rds/aurora/faqs/

"Each 10GB chunk of your database volume is replicated six ways, across three Availability Zones."

So, if there has been a storage layer failure, most likely it was a software bug in Aurora itself.
