At 7:10am ET today, our DNS provider, Dyn DNS, detected a globally distributed denial of service (DDoS) attack against its servers. This attack limited Dyn's ability to resolve its customers' domain names, causing outages across many popular internet sites. Unfortunately, the knewton.com domains were among the many that were affected. In the time since detection, Dyn engineers have managed to mitigate the attack and bring service back online. Knewton's domains were back online as of 9:12am ET. During this window, and depending on client-side DNS cache settings, Knewton partners and customers may have been unable to reach the Knewton service. We apologize for any inconvenience this may have caused and will be working diligently in the coming days and weeks to ensure we are resilient to these failures in the future
