123-Reg

123-Reg is a web hosting provider headquartered in the United Kingdom. The company offers website hosting services that allow customers to publish and maintain online sites. It also provides email hosting, enabling users to send and receive messages through custom domains. Customers access their services via a control panel interface for managing hosting settings. The provider serves a range of clients seeking reliable web and email infrastructure.

123-Reg has been subject to multiple high‑volume distributed denial‑of‑service (DDoS) attacks, as noted in incidents from 2016 and 2017. The August 2016 attack targeted its primary data center, disrupting website access, control panel availability, and email services. The January 2017 DDoS event similarly impaired customer email access and website functionality. In both cases the company acknowledged the incidents publicly and described mitigation efforts such as traffic rerouting. Service was restored after the attacks were mitigated, though some users reported lingering connectivity issues. The provider has apologized for the inconvenience caused and highlighted its ongoing work to improve network resilience. These events illustrate a distinguishing characteristic of the organisation: a history of being targeted by large‑scale DDoS campaigns and the corresponding need for robust mitigation capabilities.
