We run our validators on multiple hosting providers distributed across different jurisdictions in Latin America. We ensure availability by deploying redundant infrastructure, balancing loads and continuously monitoring specific metrics that trigger alerts in order to take corrective actions.
For our staking infrastructure we have set up a multi server architecture that guarantees the isolation of the validating nodes. The access to the servers is managed by a jump-host that not only restricts logins of unauthorized personnel but also records user entries for transparency and accountability.
The signing keys are stored in a hashicorp vault that can only be accessed through the jump host and 3 unseal keys and one token is required to obtain access. Moreover, the vault can only be entered using a specific port known only by three members of our team.
