UPDATE: We have restored our Web Hosting platform to regular service. Our teams will be reviewing logs and monitoring data to better coordinate future responses to attacks and improve resiliency.
Starting around 4:30pm PST today, our Operations team noticed a pattern of requests matching a distributed denial-of-service attack directed at our web hosting cluster. As a result, hosted websites, including pages at users.sonic.net, have suffered from intermittent availability. Both our Network and Systems teams are currently working on mitigation measures to slow down and stop the attack on our services.
