When you rent a server, you rarely get to choose the exact location where it runs. Yet, this is one of the most crucial decisions for the performance, reliability, and protection of your data. At OuiHeberg, this choice is anything but trivial: our French servers are hosted in Marseille, in one of the best-connected data centers in the world. Here’s why this specific location truly changes your project’s experience, from response time to data sovereignty.
Marseille, digital gateway to three continents
We often imagine the heart of the Internet in Paris, London, or Frankfurt. However, a shift has occurred in recent years: Marseille has become one of the world’s top Internet hubs. The reason lies in its geography. The city is the landing point for about fifteen international submarine cables, those fiber optic highways that carry almost all global traffic across the ocean floors.
From Marseille, these cables reach out to around forty countries across the Mediterranean, Africa, the Middle East, the Indian Ocean, and even Asia. While most European data centers are excellent distribution points for Western Europe, Marseille plays a unique role: that of a bridge between European digital content and Internet users in Africa, the Maghreb, and the Middle East. No other French city holds this position.
For you, this has very concrete implications. A server in Marseille is not just “in France”: it is plugged in as close as possible to the world’s major backbones. Traffic takes short, direct routes, without unnecessary detours through other capitals. This is an advantage that few hosts can truly claim, because it cannot simply be declared, it depends on the physical location where your data resides.
Latency: the detail that changes everything
Latency is the time it takes for information to make a round trip between your server and its user. It’s measured in milliseconds, and you mostly notice it when it’s bad: a site that responds with a delay, a game that “lags,” an application that feels sluggish. It directly depends on the distance and quality of the network path.
This is precisely where Marseille’s position becomes a strategic asset. For a French and European audience, the city offers excellent response times. But its real differentiator appears as soon as your audience extends beyond Europe: towards North Africa, West Africa, or the Middle East, a Marseille server is often closer, in network time, than a Parisian or Northern European server. The cables start here: so do your packets.
Whether you’re hosting a high-traffic website, a business application, a game server, or an automation platform, this network proximity is felt in your users’ experience. And if your audience is spread across several regions, the choice of location deserves real consideration, this is the topic we detail in our guide to choosing the right server location.
Our data center: Digital Realty MRS2
Let’s get specific. Our French servers are hosted within the Digital Realty MRS2 data center in Marseille. This is not an anonymous facility: it’s a carrier-grade infrastructure, designed for high availability, with 4,400 m² of equipable space and an electrical connection capacity of 16 MW. Power redundancy, strict access control, multiple connectivity options: the fundamentals of a professional data center are all present.
This choice illustrates a fundamental difference. A reseller simply rents servers somewhere and sublets them. A host that controls its infrastructure, on the other hand, knows exactly where your data runs, in which building, on which network. This control is what allows us to keep our uptime commitments and to tell you, clearly, where your VPS server lives.
Cooling without waste: the “river cooling” of the Galerie de la Mer
A data center generates heat. Thousands of servers running continuously produce a huge amount of heat, and cooling it traditionally represents a massive share of electricity consumption, often via very power-hungry chillers. In Marseille, a remarkable solution has been implemented: river cooling, or water-based cooling.
The principle is as elegant as it is ingenious. Beneath the city flows water from old coal mines, channeled since the late 19th century through an underground gallery, the Galerie de la Mer, dug between 1885 and 1907 to drain mining water to the Mediterranean. This water circulates at a constant temperature of about 15°C year-round. The data center runs it through a network of heat exchangers (27 in total, supplied by 3 km of pipes) to remove server heat, without using electric chillers.
The numbers speak for themselves: this system saves around 18,400 MWh per year, avoids about 795 tons of CO₂ annually, and is nearly 30 times more efficient than traditional cooling. It allows the site to achieve a PUE (power usage effectiveness) of about 1.2, an excellent value for the industry. Hosting your server in Marseille means benefiting from an infrastructure with a significantly reduced environmental footprint, a cooling system powered by a 19th-century industrial legacy serving 21st-century sustainability.
Your data in France: a matter of sovereignty
The hosting location is not just a matter of speed and ecology: it’s also a legal issue. Data hosted in France is subject to French and European law, notably the GDPR. This protects you from a number of uncertainties that hang over data entrusted to infrastructures under non-European jurisdictions.
For many businesses, administrations, and freelancers, this point has become crucial: knowing where data is physically stored, under which jurisdiction, and with what guarantees. Hosting in Marseille provides a clear answer to this question. We detail the concrete issues, GDPR, sovereignty, what it really changes for your business, in a dedicated article on hosting and data protection in France and Europe (article coming soon).
A controlled infrastructure, not reselling
What makes this story credible is that it’s based on real infrastructure, which we operate ourselves. OuiHeberg has its own network (AS208226), ensuring end-to-end controlled connectivity rather than outsourcing. And our fleet across our sites currently represents over 204 TB of RAM, more than 845 TB of SSD/NVMe storage, and over 13,658 processor cores in production.
These figures are not meant to impress: they simply mean that behind a Linux VPS or a Windows VPS, there is real hardware, in identified data centers, on a network we administer. That’s the difference between a host and an intermediary.
Marseille, but not only
Marseille is our French anchor, and for many projects it’s the ideal choice. But not all audiences are the same: depending on whether you’re targeting Central Europe, the Benelux, or the North American market, another location may be more relevant. That’s why we also operate data centers in Frankfurt, Amsterdam, and New York, each with its own strengths.
How do you choose between these cities based on your project, your audience, and your latency constraints? That’s the focus of our comparative location guide (article coming soon), with concrete latency measurements and use cases by city.
In the meantime, if your project targets France, Southern Europe, Africa, or the Middle East, the choice is simple: Marseille ticks all the boxes, global connectivity, controlled latency, eco-friendly cooling, and data under French jurisdiction.
