Today, WorldAPP services, including Key Survey, Form.com and associated applications, have been subject to a service disruption. Below is a brief overview of what caused the issue and the actions we’re taking to restore services as quickly as possible.

Recently, a CPU on one of the servers that our applications use to access our database started failing. Whilst the failure of one CPU doesn’t cause disruption to our services, it does require maintenance so that should the others fail, our applications aren’t impacted. Yesterday evening, our team migrated services to our disaster recovery environment to enable the required maintenance to take place. This is common practice during periods of maintenance to enable continuation of service and has been regularly implemented without effect.

After a few hours of operating on the disaster recovery environment, for reasons yet unknown, the disaster recovery environment failed. Our team took immediate steps to bring the environment back online and are working very hard on restoring services in order of priority, with the most critical services being the first to be restored. As this process continues, we’ll provide further updates on our community pages here.

As we continue to experience service disruption, our applications will remain unavailable and respondents attempting to complete a survey or form will be directed to an error page. We are incredibly sorry for the frustration that this disruption is causing you, and assure you we’re working as hard as we can to restore full service as quickly as possible.

Yours sincerely,
Teresa Crisci
Director of Client Services
