OVH, legally OVH Groupe SAS, is a French cloud computing company which offers VPS, dedicated servers and other web services. As of 2016 OVH owned the world’s largest data center in surface area.[5] As of 2019, it was the largest hosting provider in Europe,[6][7] and the third largest in the world based on physical servers.[8] The company was founded in 1999[1] by the Klaba family and is headquartered in Roubaix, France.[9] OVH is incorporated as a simplified joint-stock company under French law.


History and growth[edit]

OVH was founded in November 1999[1] by Octave Klaba, with the help of three family members (Henry, Haline, and Miroslaw).


In October 2016, OVH raised $250 million in order to raise further international expansion.[10] This funding round valued OVH at over US$1 billion. In the fiscal year of 2016, OVH reportedly had €320 million in revenue. In 2018 OVH announced its five-year plans to triple investment starting in 2021. Which represent between 4.6 and $8.1 billion U.S. dollars (4 to 7 billion euros).[11]


As of 2018, OVH had 27 data centers in 19 countries hosting 300,000 servers.[12] The company offers localized services such as customer service offices in many European countries, as well as in North America, Africa, and Singapore.[13] As of 2019[update], OVH is considered one of the largest cloud computing providers in the world, with over a million customers and one of the largest OpenStack deployments in the world.[14]

As of 2017, OVH was known for its offering of email hosting service,[15] considered one of the largest in the world,[16] in addition to its general Internet hosting services.

OVH uses in-house design and manufacturing, including custom-made servers (based on standard components) and a modular shipping container architecture. In 2019, the Canadian data center (Beauharnois, Quebec) was considered a leading example of the OVH model.[17]


As of 2016, OVH was one of the sponsors for Let’s Encrypt, a free TLS encryption service,[18][19] and OVH’s hardware supplier is Super Micro Computer Inc.[20]


In March 2021, OVH suffered a large fire at its datacenter in Strasbourg, France.[21] SBG2 had been built in 2016 with a capacity of 30 thousand physical servers.[22] SBG2 was declared a total loss, with early reports indicating damage to SBG1, and services across all four Strasbourg locations experiencing disruptions.[23] The company’s chairman, Octave Klaba, took to Twitter to confirm that all its staff were safe.[24], SBG1 was damaged partially while SBG4 remained intact, and SBG3 intact but without power, though the servers at the latter sites were taken offline temporarily.[25][24]

In total, 3.6 million websites were taken offline,[26] including “government agencies’ portals, banks, shops, news websites”.[21] For the video game Rust, a total loss of user game data was reported.[27][28]

The cause of the fire – although not confirmed – is believed to be the result of a failure of a Uninterruptible Power Supply (UPS)[citation needed]



In December 2010, French Gizmodo edition revealed that WikiLeaks selected OVH as its new hosting provider, following Amazon‘s refusal to host it.[29][30][31] On December 3, the growing controversy prompted Eric Besson, France’s Industry Minister, to inquire about legal ways to prohibit this hosting in France. The attempt failed. On December 6, 2010, a judge ruled that there was no need for OVH to cease hosting WikiLeaks.[32] The case was rejected on the grounds that such a case required an adversarial hearing.[33]

Information disclosure and multiple vulnerabilities[edit]

In January 2019, the magazine WebsitePlanet uncovered client-side vulnerability in some of the largest hosting companies in the world: Bluehost, DreamHost, HostGator, iPage and OVH.[34]

Environmental impact[edit]

OVH started to integrate innovative water cooling in 2003[35] in its datacenters.

OVH relies in large part on nuclear power, in particular their Gravelines data centre is known for being located next to the Gravelines Nuclear Power Station.[36][37]

In January 2021, OVH with other industry players joined the Climate Neutral Data Centre Pact, which is a pledge to achieve climate neutrality of datacenters before 2030.[citation needed]
