With two fully independent DWDM paths &#8211; routed via Belgrade and a diverse route through Romania &#8211; the site has been engineered to provide path diversity, automated failover, and consistent low-latency performance. It is fully integrated into GNM\u2019s meshed DWDM backbone, which provides onward connectivity to major European hubs including Bratislava, Frankfurt, Amsterdam, Vienna, Prague, Warsaw, and Stockholm.<\/p>\n\n\n\n<p>The node also offers access to a full range of services, including high-capacity 100G and 400G DWDM transport, direct and remote access to GNM-IX, IP Transit with BGP community-based policy control, and Layer 2 services backed by strict service-level guarantees.<\/p>\n\n\n\n<p>\u201cThe Sofia upgrade is an important step in the ongoing development of GNM\u2019s core infrastructure in the region. One of the first customers to use the new platform was a European network operator that provisioned a 100G DWDM service over both available paths, along with a GNM-IX peering connection. The deployment delivered a measurable reduction in latency to Frankfurt, around 18%, and significantly improved recovery times during incidents. It\u2019s a clear example of how infrastructure investment directly enhances service performance for our clients,\u201d said Alex Surkov, Head of Developm<\/p>\n","protected":false},"excerpt":{"rendered":"<p>GNM has completed the modernisation of its point of presence in Sofia, deploying the Arista 7800R3 &#8211; a modular, carrier-grade platform with native 400G capability.
