RabbitMQ, even a single-node RabbitMQ, has a hard time going down. You are more likely to have your server/container go down long before RabbitMQ node goes down. That being said, if you want to have a clustered solution with nodes being in different DCs, configure shoveling (https://www.rabbitmq.com/shovel.html https://www.rabbitmq.com/shovel.html) or for a simpler solution, use a private VPN to interconnect the RabbitMQ nodes. I would go for the latter.
