Never lose your data. ### 99.9% uptime SLA Under 44 minutes of allowed downtime per month. We aim for zero. [Read full SLA.](https://blnkfinance.com/legal/deploy-sla) ### Zero-downtime backups Automated backups on the live instance. Restore without taking the ledger offline. ### High availability Automated failover. If a node goes offline, our systems bring the deployment back automatically. ### We migrate your instance Already on Core? We move that instance onto Cloud with you. Balances and history come over. No rebuild. ### Choose your region Pick where your instance runs at deploy time. Your ledger and backups stay in that region for data residency. ### IP whitelisting Restrict which IP addresses can reach your Production instance. Only traffic you allow gets through. > For four years we billed on bare Postgres: one transaction in, another out, no balances. It wasn't a ledger. On Blnk, everything is accounted for and auditable. There hasn't been a case where money went missing. We can add new features easily, and expand into more currencies without rebuilding.
