How big is metaserver these days?
I might run three deployments at each data center: the primary, and secondaries for two other regions. Replicate between them at the block device level, bypassing the mysql replication situation entirely (except for on-disk consistency requirements of course).
Of course this comes with a 3x increase in service infrastructure costs because of the two backups in each data center that are idle waiting for load.

I read the Atlas blog post, which implied that metaserver was rearchitected, but still 3M SLOC of Python. https://dropbox.tech/infrastructure/atlas--our-journey-from-a-python-monolith-to-a-managed-platform https://dropbox.tech/infrastructure/atlas--our-journey-from-...
