Even not using the proprietary AWS services, migrating from one to another cloud hosting provider - and which one will take their business now? - isn't easy. Not only for the size of the data store (50-70 TB?) but many development, testing, deployment and operating processes need to be retrofitted to a new infrastructure provider. I guess they didn't pro-actively plan for this. They can consider themselves very lucky and capable if it can be done within a week, but I think it'll take longer.
