Our (hi)story

1&1 was born in 1988, with the main aim of making information technology easy for everyone to understand and use. Committed to delivering a powerful, reliable, and secure product, 1&1 engineered its own data center architecture and extensive network with locations in Europe and the US, enabling millions of clients to get online, build up their web presence and take advantage of increasingly more sophisticated digital services.

This launch of mass-market hosting, combined with years of experience building server hardware tailored for cloud applications, was complemented by strategic acquisitions to create a full-fledged hosting leader. 1&1 cemented its position as the provider of world-class hosting solutions and largest domain registrar in Europe.

Robust infrastructure portfolio in hand, 1&1 then integrated cloud-based digitization applications and tools into its offering, enabling businesses of any size to safely and simply take advantage of the benefits of the cloud.

Becoming 1&1 IONOS

In 2018, to build upon its vision of empowering businesses to leverage the latest digital technologies, 1&1 combined its web hosting, applications and server product lines with ProfitBricks’ cloud infrastructure solutions, becoming IONOS and reaffirming its dedication to innovation and customer centricity.

Proud of its heritage, IONOS will continue its mission: to make powerful technology work for everyone, and to deliver the best of cloud computing.

IONOS is a member of the United Internet group.

1&1 IONOS is now IONOS

Evolution, not revolution — from January 2020, we will be known as IONOS. We will continue to be the 1&1 brand you know, but with a new logo that better represents the innovation, reliability and experience you expect. Your access to our products and services remains unchanged and you can continue to enjoy first-class web hosting, fully scalable cloud solutions and individualized support.
