Top priorities for Nodes.Guru are reliability and security. This is achieved by the following means:
– we mostly utilize bare metal machines with some portion of cloud services provided by OVH, Latitude, Vultr, DigitalOcean, Hetzner, AWS
– new instances go through custom setup procedures to enhance security (hardware tests, user and server access policies, firewall, package updates and installation etc)
– monitoring and alert system consisting of Zabbix, Grafana+Prometheus + custom web app + telegram and discord bots with 24h on-call DevOps
– node setup has hot failovers, sentries and MPC setup for tm-based networks
– if things go wrong way – disaster recovery procedures and 100% slash-compensation
