Heroku > Railway: MongoDB Cloud Atlas Charges Tripled (Data Transfer Internet Charges)

We would love to figure out how to resolve this issue. When we migrated from Heroku to Railway, our typical MongoDB Atlas instance was about $250 per month.

Since migrating, our bill has more than tripled (most recent being $850) with 100% of the change due to the "Data Transfer: Atlas AWS Internet Transfer" charges.

MongoDB Atlas Instance: AWS / N. Virginia (us-east-1)
Railway App Instance: US East (US, Virginia)

Is there something we are missing here? Are railways app not in the AWS instances?

Railway does not run on AWS, they currently run on GCP.

Second question: Can I move my mongo database to Railway?

If you are okay with managing your own database and don't need replication, absolutely!

Running your database on Railway and connecting to it via the private network eliminates all database <--> service egress fees.
