Description:
A series of DDoS attacks on our DNS system has been rendering domains inaccessible since Tuesday night (December 9th, 2014).

While we have already taken steps to resolve this issue, availability may remain limited.

We apologize for any inconvenience caused.

Description:
Yesterday afternoon at 4pm EST an unknown third party initiated a DDoS attack on 1&1’s DNS infrastructure. The Domain Name System (DNS) is used to attribute internet addresses such as “1and1.com” to IP numbers, similar to a telephone book. During the coordinated attack, many widely spread computers (also known as bot net) sent several hundred thousand requests per second to our DNS servers. The attack resulted in reduced availability on some of our hosting services (such as shared hosting, MyWebsite, servers, e-mail, control panel). Our engineers swiftly identified the target of the attack and have initiated respective countermeasures, making the majority of affected services now fully available. A small number of our customers may still encounter limited availability of their domain names. We are prioritizing work to fully resolve the issue as promptly as possible and apologize unreservedly for any inconvenience. Please continue to check status-1and1.com for additional information.
