UDP checks from Romania send a packet from our Bucharest or Bacău node to your specified port and wait for a response. Neither FlokiNET nor Telesystem apply unusual outbound UDP filtering on their datacenter connections, so a no-response result reflects the destination firewall policy rather than a Romanian network restriction. This check is useful for testing VPN endpoints, game servers, SIP gateways, and DNS resolvers from a Southeastern EU perspective.

Romania's fast broadband infrastructure and geographic position make it a relevant UDP test location for services targeting Eastern and Southeastern EU users. Latency from Bucharest to Sofia is around 15 ms and to Budapest around 20 ms. For services running VPN or game server infrastructure trying to cover this region efficiently, UDP test results from our Romanian nodes confirm both reachability and the base latency users in the region experience.

A UDP failure from Romania while TCP succeeds on the same host means UDP is filtered at the destination. A failure on both protocols from both Romanian nodes while Western European nodes succeed suggests Romanian IP space is blocked. Since both nodes are on different ASNs (AS200651 and AS214062), a failure on both from Romania specifically — rather than just from one AS — strengthens the conclusion that it is a country-level or regional IP block rather than an ASN-specific rule.

Bucharest is the center of Romanian internet infrastructure. RONIX and InterLAN are the primary internet exchanges, with Equinix also operating a colocation and peering facility in the city. Romania has one of the highest average broadband speeds in Europe — consistently ranking in the top five for fixed broadband download speeds in EU comparisons. This is partly due to early investment in fiber-to-the-home by smaller competitive ISPs in urban areas, which created a dense fiber market before large incumbents dominated.

The major Romanian ISPs include RCS&RDS (AS8708), which is the largest broadband provider and operates a national fiber backbone, Orange Romania (AS9050), Telekom Romania (AS8953), and UPC Romania (AS6830, now Vodafone). RCS&RDS is particularly notable from a network perspective — it peers aggressively at European IXPs and has built transit infrastructure that competes with incumbents across the region. Its AS8708 appears frequently in traceroutes through Romania and neighboring countries.

InterLAN operates both an IX and carrier-neutral datacenter infrastructure in Bucharest. Equinix's Bucharest facility brought a globally recognized neutral colocation brand to the Romanian market and connects to Equinix's European fabric. These facilities have attracted regional hosting operators and CDN edge nodes, improving local content delivery for Romanian users and reducing reliance on Frankfurt or Vienna for content that was previously served from further west.

Bucharest's geographic position gives it reasonable latency to several important neighboring cities. Sofia is around 15 ms away, Budapest is roughly 20 ms, Belgrade around 20 ms, and Frankfurt around 40–45 ms. This places Bucharest within the Central European latency envelope for most practical purposes, making it a viable location for services targeting Southeastern EU users who want sub-20 ms local response times and EU-compliant hosting jurisdiction.

We operate two probe nodes in Romania. The first is in Bacău (northeastern Romania) on AS214062 via ITITAN HOSTING / Telesystem. The second is in Bucharest on AS200651 via FlokiNET. These nodes represent different geographic and network positions within Romania. Bacău is in the northeast, reflecting conditions for users in Moldova-border regions and northeastern Romania. Bucharest reflects the capital's IX-connected infrastructure. Running checks across both nodes gives a view of intra-country routing variation rather than just a single Bucharest-centric perspective.
