OVH is a worldwide, privately owned web hosting service company that provides dedicated servers, mutual hosting, domain names and VOIP telephony services. The company is a société par actions simplifiée under French law and its headquarters are in Roubaix in northern France.

The company has twelve datacentres[1] housing at least 160,000 machines.[2] The company offers localized services in France,[3] Germany,[4] Italy,[5] Poland,[6] Spain,[7] Ireland,[8] United Kingdom,[9] the Netherlands,[10] Lithuania,[11] and Finland.[12] It has also expanded its services to the United States of America and Canada.[13][14] The company has deployed IPv6 and DNSSEC.[15][16]


OVH was founded in 1999 by Octave Klaba (fr), at the time a third year student at Institut catholique d'arts et métiers (fr) (ICAM) in Lille. The name comes from the abbreviation of his nickname, Oles Van Herman. It also serves as a backronym for "On Vous Héberge", meaning "We Host You" in French.

In 2001, OVH rented 7 racks from Paris hosting provider Claranet. With its expansion, more room was needed and cooling became an issue, so OVH moved to an abandoned datacenter from Free, a French ISP. In 2002, another datacenter from Free was rented by OVH, who then bought its building for its first own datacenter in Paris.

In 2006, OVH opened its first subsidiaries, beginning with Poland, Senegal and Spain.



OVH hosted a website of the Democratic Forces for the Liberation of Rwanda (FDLR), a Hutu rebel force, until September 2009 when a German reporter asked it why it was hosting the site.[17][18]


In December 2010 WikiLeaks installed itself on the servers of OVH in France.[19] France's Industry Minister Eric Besson said in a letter to the CGIET technology agency, that WikiLeaks "violates the secret of diplomatic relations and puts people protected by diplomatic secret in danger" and was therefore "not acceptable" that the site was hosted on servers based in France. The minister asked for measures to bar WikiLeaks from France.[20] In response, OVH referred the topic in emergency to a judge[21] in order to get a clear and definitive answer about whether hosting WikiLeaks is legal.

On December 6, 2010, the judge decided that there was no need for OVH to cease hosting Wikileaks.[22] The case was rejected on the grounds that such a case required an adversarial hearing.[23]

OVH managing director Octave Klaba commented that: "OVH is neither for nor against this site. We neither asked to host this site nor not to host it. Now it's with us, we will fulfill the contract."[24]

Bitcoin Provider Attacks[edit]

During the week of April 21, 2013, accounts on at least two separate Bitcoin providers websites hosted on OVH servers were compromised. The separate attacks occurred two days apart.

The account passwords were reset, and the servers were restarted into recovery mode, giving the attackers full access. The firms whose sites were hacked insist they never initiated a password reset (which requires an email confirmation). OVH confirmed that 3 customers were victim of a vulnerability in their password recovery unique URL system, as it was not generating as randomly as intended, meaning that an attacker could get the correct code via brute force.[25]

News attacks[edit]

In 2013, OVH was attacked by hackers. A database of all European customers (name, phone, hashed password...) was stolen.[26]

Notable technical issues[edit]

In 2013, the network of the oldest datacenter (RBX1) was down for 4 hours.[27] OVH then offered a week of hosting for the clients affected by the downtime.

Abuse reports[edit]

As of April 2014, The Spamhaus Project lists OVH among the top 10 of "The World's Worst ISPs", due to continued provision of internet services to spammers.[28]
