Reliability of National Internet Segments
The connectivity of Internet at the network layer is a result of interaction between autonomous systems (AS), and it is more stable the more alternatives routes between ASNs there exist, which is basic fault tolerance principle. This research shows how outage of single, though significant AS affects the global connectivity of the region.

Qrator Radar team is pleased to announce a new feature of our network scanner: we begin to detect hosts with vulnerable ports in your network. At this moment we are detecting open TCP ports of BGP network protocol. This protocol is often used by network devices (especially border routers), and generally access to these devices should be restricted using ACL. If such port is open for everyone, it is a serious vulnerability which can be used by attacker to cause denial of service of the network device, which can in turn cause outage of whole networks.
