TCP checks from Budapest (AS9009, M247) attempt a SYN-ACK handshake to your host on a specified port and measure time to completion. M247 does not apply outbound port filtering on commercial hosting connections. This makes our Hungarian TCP probe a clean signal of what your firewall and routing present to Central European hosting traffic — any failed check indicates the block is on the destination side or in transit, not the probe.

TCP handshake times from Budapest: to Vienna approximately 13–17 ms, to Frankfurt approximately 30–38 ms, to Warsaw approximately 18–22 ms, to Belgrade approximately 18–22 ms. These are the baseline connection setup costs for services targeting Hungarian or Central European users. For latency-sensitive applications such as database connections, game backends, or financial APIs, knowing these baselines is essential for setting realistic SLA thresholds.

A failed TCP check from Hungary when the same port succeeds from Western European nodes typically means one of: the IP is geo-blocked for Eastern Europe, the ASN (AS9009) is on a firewall denylist — which would be unusual given M247's legitimate commercial standing — or there is asymmetric routing causing the return path to fail. Cross-referencing against our Austrian and German nodes will quickly distinguish a Hungary-specific block from a broader routing fault.

Budapest is the central internet hub for Hungary and a significant regional interconnect point for Central and Eastern Europe. BIX (Budapest Internet Exchange) is Hungary's primary national IX and routinely exceeds 400 Gbit/s peak throughput, making it one of the larger internet exchanges in the CEE region. BIX connects Hungarian ISPs, international carriers, CDN providers, and cloud networks under one peering fabric, which keeps a large share of Hungarian traffic local rather than routing through Vienna or Frankfurt.

Our probe node runs on AS9009 (M247 Europe SRL) in Budapest. M247 is a large pan-European hosting and transit provider with infrastructure across multiple EU countries. AS9009 maintains extensive upstream and peering relationships, sourcing transit from major tier-1 carriers and participating in multiple European IXPs. This gives our Hungarian probe diverse routing paths to most European and global destinations, making it representative of what a well-connected Budapest-hosted server sees.

Latency from Budapest to other major European hubs: Vienna approximately 13–17 ms, Warsaw approximately 18–22 ms, Bratislava approximately 10–14 ms, Belgrade approximately 18–22 ms, Bucharest approximately 22–28 ms, Frankfurt approximately 30–38 ms, Amsterdam approximately 42–50 ms, London approximately 55–65 ms. Budapest's central position in the Pannonian Basin means it has short terrestrial paths to Austria, Slovakia, Serbia, Romania, and Ukraine simultaneously — a useful geographic characteristic for regional routing.

The Hungarian ISP market is dominated by Magyar Telekom (AS5483), the national incumbent, and DIGI (AS20845), which has grown rapidly as a cable and fiber provider. Vodafone Hungary and Yettel serve mobile and broadband segments. On the hosting side, M247 (AS9009), DataCenter Hungary, and Compu-Consult operate colocation in Budapest. M247's Budapest facility is carrier-neutral and well-connected to BIX. The Hungarian CDN market is active, with Cloudflare, Akamai, and Hungarian domestic CDN operators all maintaining Budapest presence — which means cached content is generally served from a local Budapest edge for Hungarian users.

Hungary has a mature and competitive colocation market by regional standards, partially driven by EU data sovereignty requirements that have pushed some local enterprises to prefer Hungarian-hosted infrastructure. The BIX exchange community includes a substantial number of content networks and CDNs with direct peering, which keeps Hungarian users's latency to major content platforms unusually low compared to smaller Balkan countries that must route to Vienna or Frankfurt for the same content. Running checks from our Budapest node gives you a reliable view of Central European connectivity.
