Our network is based on professional high-performance carrier-class equipment. Cisco 3750x switches with 48 1-Gbps and 2 10-Gbps ports are used for clients' servers. And Juniper MX960 routers are responsible for routing – they work under the N+1 scheme (in case of router failure, it’ll be replaced by backup one). For the best reliability, we use such scheme throughout our network (including operators).
Below is a list of Exchange / Peering carriers. We use only Tier-1 and Tier-2 providers.
