Ping from the French nodes measures ICMP round-trip time from two distinct locations and ASNs. From Gravelines (OVH), expect around 12ms to London, 11ms to Frankfurt, and 8ms to Brussels. From Paris (DataCamp), distances are slightly different but in the same ballpark — Paris to London is typically 12ms, Paris to Frankfurt 11ms, Paris to Amsterdam 15ms. To the US East Coast, both nodes will show RTTs in the 85–95ms range.

Comparing ping results between the Gravelines and Paris nodes for the same target is worth doing when you suspect routing issues on a specific French network. OVH has its own extensive peering and tends to take direct paths to most European destinations. DataCamp uses different upstream transit. If the two nodes show very different RTTs to the same target, the path diversity between them has exposed a routing difference — dig into the MTR output to see where the paths diverge.

OVH's network in particular is known to apply ICMP rate limiting on some paths and internal segments. If ping from the Gravelines node shows packet loss to a target that is clearly reachable (you can load a website hosted there), don't assume the loss is real — run a TCP or HTTP check to the same target to get a cleaner measurement of actual reachability. ICMP de-prioritisation on OVH backbone links is well-documented and a common source of false-positive ping alerts.

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.
