Moving a project takes several minutes.
Your project is not
hosted on a networked filesystem, which would be too slow to
operate between datacenters; instead, there are two copies
of your project hosted in each datacenter as a ZFS filesystem,
distributed using
consistent hashing, and synchronized using ZFS replica streaming.
Moving your project
involves closing the project on its current host, then opening
a replica of it on another randomly chosen host (with newest
snapshot).
