Controversies and Incidents

2021 Strasbourg Data Center Fire

On March 10, 2021, at approximately 00:47 CET, a fire erupted in the SBG2 operated by OVHcloud in , , completely destroying the facility and partially damaging the adjacent SBG1 building. The blaze, which lasted several hours, affected one of four data centers on the site, with SBG3 and SBG4 remaining operational. SBG2, constructed in with a capacity for around 30,000 physical servers across its five stories, housed for numerous customers, leading to widespread outages for approximately 3.6 million websites and services. No injuries or casualties occurred during the incident. The precise cause of the fire remains undetermined following investigations, though preliminary analyses pointed to potential failures in (UPS) systems, including repaired units, or a water leak from a cooling inverter. The French Bureau d'Enquêtes et d'Analyses pour les Risques Incendie (BEA-RI) released a report in June 2022 detailing the event but could not conclusively identify the ignition source, citing factors such as rapid spread possibly exacerbated by design elements like wooden ceilings and configurations. OVHcloud committed to transparency but delayed full disclosure pending legal and insurance proceedings, with CEO Klaba attributing some propagation risks to non-standard construction choices made for efficiency. The incident resulted in significant for some customers whose backups were stored onsite or inadequately replicated elsewhere, disrupting operations for businesses reliant on OVHcloud's public cloud and hosting services. French courts subsequently ruled against OVHcloud in multiple cases, rejecting defenses and deeming backup practices insufficient; for instance, one decision mandated payments exceeding 400,000 euros to affected parties hosting EU , emphasizing contractual obligations for . In response, OVHcloud enhanced , protocols, and site-specific risk assessments across its , while facing ongoing litigation and scrutiny over reliability. The event underscored vulnerabilities in concentrated designs, prompting industry discussions on diversified geographic backups and non-combustible materials.

WikiLeaks Hosting and Regulatory Pressures

In December 2010, shifted its hosting to OVH servers in after terminated its services amid political pressure from U.S. authorities. The organization ordered a dedicated server with DDoS protection through OVH's website, paying less than €150 via credit card, as confirmed by OVH managing director Octave Klaba. This arrangement positioned OVH, a French provider, as a temporary refuge for the site during a period of intense scrutiny following ' publication of U.S. diplomatic cables. The French government swiftly applied regulatory pressure, with Industry Minister Éric Besson demanding on December 3, 2010, that be barred from French servers to prevent the country from becoming a hub for cyber threats or controversial content. Besson argued that hosting the site violated French interests and urged OVH to cease services, framing the issue as a concern rather than a judicial matter. OVH resisted, with Klaba stating that decisions on site closure belonged to the courts, not politicians or the company itself, and announced it would seek a judicial ruling on the site's legality under French law. A court in subsequently declined to compel OVH to shut down the hosting, affirming that OVH was not obligated to act without a legal determination of illegality. Despite this, relocated its primary operations to a Swedish provider, , by early December amid ongoing DDoS attacks and sustained governmental scrutiny, limiting OVH's role to a brief period of about two to three days. The episode highlighted tensions between commercial hosting providers and state authorities, with OVH's initial defiance underscoring its commitment to operating as neutral rather than content arbiter, though it faced subsequent international surveillance, including monitoring of Klaba by British intelligence linked to the fallout.

DDoS Attacks and Other Operational Challenges

OVHcloud has faced numerous distributed denial-of-service (DDoS) attacks, testing the resilience of its always-on mitigation infrastructure designed to filter malicious traffic without service interruptions. In October 2016, the company endured a volumetric assault from the Mirai botnet, involving over 152,000 compromised devices, which generated massive inbound traffic volumes aimed at overwhelming network capacity. A more advanced challenge emerged in April 2024, when OVHcloud neutralized a record 840 million packets-per-second (Mpps) DDoS attack comprising TCP ACK floods from roughly 5,000 source IP addresses and DNS reflection amplification, with two-thirds of packets transiting four U.S. points of presence via hijacked routers. The company employed FPGA-accelerated hardware and DPDK-optimized networking to scrub the , preventing , though the attack's sophistication—exploiting router vulnerabilities for high packet rates—highlighted evolving threats from botnets targeting amplification vectors. The year 2024 saw intensified network-layer DDoS activity, including a two-week campaign delivering over 40 assaults surpassing 2 terabits per second (Tbps), alongside a surge in packet-rate attacks since early 2023 that strain core routing resources by flooding with small-packet barrages. These events demanded continuous infrastructure scaling and real-time anomaly detection, as OVHcloud's systems automatically divert suspect traffic to scrubbing centers for analysis and cleansing, a process that, while effective, incurs substantial operational overhead in traffic engineering and threat intelligence. Beyond DDoS, OVHcloud has dealt with sporadic network faults and service degradations, such as connectivity disruptions at data centers like Vint Hill, investigated and resolved through targeted interventions. User-submitted reports on platforms like indicate intermittent outages concentrated in regions with high service density, often linked to backbone routing or issues, though OVHcloud maintains uptime tracking and proactive monitoring to address root causes. These challenges reflect the inherent complexities of managing a global, multi-tenant provider, where even mitigated incidents can amplify scrutiny on reliability amid competitive pressures for near-100% .

In 2020, it initiated the Open Trusted Cloud program to promote transparency, open-source interoperability, and privacy controls, aligning with CISPE's code of conduct endorsed by the for GDPR adherence and . Key milestones include obtaining the SecNumCloud qualification from France's National Cybersecurity Agency (ANSSI) for its Hosted Private in early 2021, establishing it as a benchmark for trusted, high-security services compliant with over 360 sovereignty and cybersecurity requirements. In March 2025, OVHcloud's Bare Metal Pod platform earned SecNumCloud qualification under the 3.2 framework, providing isolated, sovereign environments for sensitive workloads resistant to advanced threats. These certifications enable service to entities via frameworks like France's UGAP, the UK's , Italy's AgID, and the European Commission's DPS 1 MC5 dynamic purchasing system. OVHcloud endorses the EU Services (EUCS) scheme's High+ criteria for maximal and is pursuing certification to meet emerging EU standards.

Criticisms, Reliability Concerns, and Competitive Challenges

OVHcloud has encountered persistent reliability concerns, including service outages and hardware failures reported by users. In October 2024, the company suffered a brief but significant network outage impacting its AS16276 autonomous system, which disrupted connectivity for numerous hosted services and drew attention from third-party observers like . Independent uptime testing in 2025 revealed OVHcloud's performance falling below the industry standard of 99.9%, with recorded downtime exceeding acceptable thresholds during evaluation periods. Customer complaints on platforms like and frequently cite frequent hardware issues and inadequate redundancy, exacerbating perceptions of infrastructural vulnerabilities beyond the well-known 2021 fire. Support responsiveness represents another major point of , with users reporting delays of days or longer for issue resolution, particularly outside or for non-urgent tickets. Reviews indicate heavy reliance on automated systems, leading to frustration over lack of human intervention and unresolved billing or configuration problems. records document similar disputes, often involving service disruptions without timely compensation or fixes. These issues contribute to mixed user satisfaction ratings, averaging around 3.7 out of 5 on aggregate review sites as of late 2025. In competitive terms, OVHcloud struggles against hyperscale providers like AWS, , and Google Cloud, which dominate with over 60% combined global as of 2025. OVHcloud's share remains marginal at approximately 1.1%, limiting its ability to attract enterprise workloads requiring extensive global footprints or integrated AI/ML services. While emphasizing European , the provider faces challenges in matching the innovation pace and ecosystem breadth of U.S.-based rivals, resulting in slower adoption for complex hybrid or multi-cloud deployments. Pricing advantages in dedicated servers do not fully offset perceptions of inferior scalability and feature parity in public cloud offerings.
