Monitoring
Our systems are monitored using 2 redundant Prometheus/Alertmanager instances.
Alerts are set up for system as well as blockchain node parameters.
Alertmanager pushes alerts to a cloud paging service.
Solana
Our Solana validator is using custom state-of-the-art hardware, located in a DDoS-protected secure datacenter. This allows us to provide a high APY yield by earning high vote credits and minimize downtime during Solana version updates.
Solana service redundancy is provided by a cold-standby server, which can be activated within a maximum of 20 minutes after main server failure. We aim to switch to a hot-standby model when reaching a certain stake amount.
Oasis Protocol
Oasis validator service is enabled by 4 geographically-diverse server instances: 2 validator and 2 Emerald/Cipher paratime nodes, which are run on OVH servers.
In addition, we maintain Oasis Testnet validator/Paratime node.
SSV Network
We run SSV instance on a server with local Besu/Teku Ethereum nodes.
Backup server runs local Besu/Teku nodes with cron rsync periodically backing up SSV blockchain database from the active node.
