Cardano BG nodes are hosted in one of the most reliable Data Cener in Europe, located in Bulgaria. The network connectivity of the servers is completely redundant and all connections go through several independent network controllers and devices with direct connection to TIER 1 suppliers. The international network has six independent optic routes through our European partners and cross-border interconnects with Romania, Greece, Turkey, Serbia and North Macedonia. The redundancy is organized in an N+1 configuration which guarantees 99.995% availability of services (SLA). The content and configuration of the main server is replicated in real time on at least one other server, which can automatically replace the first in case of failure.
The servers are proteced with larger than 1Tbps DDoS Protection. Core and Relay nodes are protected with internal and external firewalls.
