MTR from the French nodes traces the full path from OVH Gravelines or DataCamp Paris to your target, revealing every router hop and per-hop loss statistics. OVH's MTR output is distinctive: the first several hops will be within OVH's own backbone before handing off to a peer or transit provider. OVH peers at DE-CIX Frankfurt, AMS-IX Amsterdam, LINX London, and France-IX Paris, so the exit point varies depending on the destination.

Gravelines-originated MTR traces heading to the UK often exit OVH's network via a direct cross-Channel path, bypassing Paris entirely. This is a good illustration of how OVH's private fibre between its northern France data centres and UK peering points creates routing that looks unusual compared to a standard transit-dependent host. If the trace takes an unexpected path, it's most likely OVH choosing an optimal internal route rather than a routing problem.

For DataCamp Paris, MTR output will show a different set of upstream transit providers. DataCamp uses commercial transit rather than the extensive private peering that OVH maintains. Comparing MTR traces from both French nodes to the same target can reveal significant path differences — different exit countries, different upstream ASNs — which explains why response times or packet loss rates might differ between the two nodes even for the same destination.

France has two nodes on this platform covering two distinct parts of the country and two very different network environments. The Gravelines node runs on AS16276, which is OVH SAS — the largest hosting provider in Europe by server count, headquartered in Roubaix in northern France. The Paris node runs on AS212238, operated by DataCamp Limited, a provider that focuses on bulletproof-adjacent hosting and operates in multiple European jurisdictions.

OVH's network is one of the more interesting in Europe. The company operates its own submarine cable and maintains extensive private fibre between its data centres in Roubaix, Gravelines, Strasbourg, and beyond. Gravelines is a purpose-built data centre campus about 40km west of Dunkirk, close to the Channel Tunnel corridor. OVH peers directly at most major European IXPs and carries a significant portion of its own transit, which means routing from Gravelines can look quite different from what you'd see on a standard transit-dependent host.

France-IX is the main French internet exchange, operating peering nodes in Paris, Lyon, and Marseille. The Paris node at France-IX handles the bulk of domestic and international peering for French networks. Paris sits roughly equidistant between London and Frankfurt, and the raw fibre distances translate to consistent latency: London to Paris typically runs 12ms, Paris to Frankfurt around 11ms, making Paris a natural midpoint for traffic flowing across the northern European backbone.

The southern France-IX nodes in Lyon and Marseille are important for Mediterranean and southern European traffic. Marseille in particular is a major submarine cable landing point — several cables connecting Europe to the Middle East, Africa, and Asia come ashore there. For traffic heading to those regions, routing via Marseille can be significantly faster than going north to Paris or Amsterdam first.

DataCamp Limited in Paris operates on a network that serves a range of hosting use cases, some of which attract abuse-focused traffic. This means the Paris node's source IP may behave differently from OVH when hitting targets with aggressive firewall rules or reputation-based blocking. Testing from both French nodes side by side is useful: if a target responds to OVH but not DataCamp, the issue is IP reputation or ASN-level blocking, not a general France connectivity problem.
