# Garage
Our S3-compatible object storage service is based on [Garage][1].
Garage is running as a cluster, with one VM each on 3 different physical hosts
in 2 different zones (data centers).
Replication mode is set to "2", meaning PUTs are always immediately synced to
nodes in 2 different zones (write/read consistency guaranteed by default).
When all nodes in one zone become unavailable, the cluster is switching to
read-only mode automatically, since the write quorum cannot be reached in that
case. If it is necessary (in an emergency) to write to nodes in only one zone,
you can change the replication mode to "2-dangerous", which lowers the write
quorum to 1.
Please refer to the [replication documentation][2] for more detailed information.
