OVH is a privately owned web hosting service company in France 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. OVH was created in 1998 by Octave Klaba, at the time a third year student at ICAM in Lille.
The company has six datacentres housing at least 120,000 machines. The company offers localized services in France, Germany, Italy, Poland, Spain, Ireland, United Kingdom, the Netherlands and Finland.  It has also expanded its services to the United States of America and Canada. The company has deployed IPv6 and DNSSEC.
Since 2012 the company has been classed as the largest server host in the world.
In December 2010 WikiLeaks installed itself on the servers of OVH in France. 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. In response, OVH referred the topic in emergency to a judge in order to get a clear and definitive answer about whether hosting WikiLeaks is legal.
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."
Bitcoin Provider Attacks 
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 re-started into recovery mode, giving the attackers full access. The firms who's 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.
Significant loss of funds occurred at both sites.
