UDP checks from North Macedonia send a packet to the target port from our Skopje probe and wait for a response. Macedonian data center traffic is not subject to UDP filtering at the ISP level. The main failure modes for UDP from Skopje are server-side: closed ports, firewall rules that silently drop UDP, or cloud security groups that do not include Macedonian source IP ranges in their allow lists.

North Macedonia is a relevant test point for UDP-based services targeting Balkan users. VPN endpoints, game servers, and SIP infrastructure that need to be reachable from the western Balkans should respond to a UDP check from Skopje if they are correctly configured. A no-response result from the UDP check is not proof of an ISP-level block — verify the firewall configuration before drawing that conclusion.

If a UDP port responds from Serbian and Bulgarian probes but not from Skopje, the issue is likely in the server's firewall or geo-block configuration rather than the Macedonian path. North Macedonia's IP space is small and distinct, and it is not uncommon for manual IP allow lists to miss it while covering neighboring countries. The UDP check from Skopje gives you direct confirmation of whether this is the case.

North Macedonia is a small, landlocked country in the western Balkans. Skopje is the capital and the sole significant internet hub. MK-IX (Macedonian Internet Exchange) is the country's only neutral peering point and is based in Skopje. It connects local ISPs and transit providers to keep domestic Macedonian traffic local. Given the country's size and the small number of participating networks, international traffic relies primarily on transit through neighboring Serbia and Bulgaria, which are the main exit points for Macedonian internet traffic.

Latency from Skopje to Sofia runs around 20 ms, and to Belgrade around 25 ms. These two cities serve as the primary transit hubs for Macedonian traffic heading west and north. From Sofia, traffic continues toward Frankfurt, Vienna, or Vienna IX (VIXP) depending on the carrier. From Belgrade, traffic typically routes toward Frankfurt via Serbia and Croatia or Hungary. Skopje to Frankfurt is around 50–65 ms on well-transited paths, though suboptimal routing or congested transit can push that higher.

North Macedonia is not an EU member state but is an EU candidate country with a closer alignment to EU regulatory frameworks than some of its Balkan neighbors. The domestic ISP market is relatively small, with Makedonski Telekom (AS9118, a Deutsche Telekom subsidiary) acting as the dominant carrier and providing a significant share of the backbone. T-2 and Blizoo (now A1) provide additional consumer broadband and business connectivity. International transit capacity is purchased from the same large European carriers that serve the broader Balkan region.

Skopje hosts the country's primary data center infrastructure, though the market is far smaller than regional centers like Sofia or Belgrade. The carrier-neutral data center landscape is limited, with Makedonski Telekom's facilities and a small number of independent operators serving local hosting demand. Cross-border fiber connections to Serbia (toward Niš and Belgrade) and Bulgaria (toward Sofia) carry most of the international traffic. These routes are fairly well-established and operate at low latency given the short geographic distances.

For operators testing connectivity into the western Balkans, Skopje represents a distinct routing zone from Serbia and Bulgaria despite the short distances. Transit paths, carrier relationships, and peering arrangements in North Macedonia are separate from those in neighboring countries. A test from Skopje gives you a view of how well your server is reachable for Macedonian users specifically, which matters if you are serving a Balkan audience or want to confirm that your server's routing covers the full western Balkan region.
