We experienced a service disruption on Tuesday November 25th 2014, which affected VoC Feedback. During this incident the VoC Feedback back-end for managing surveys was not available. The period of disruption began at 20:00 CET on November 25th 2014 and lasted until 22:00 CET the same day.
The cause of the service disruption was an issue between Cloudflare - our partner for securing VoC Feedback against attacks - and our systems. As a result of this the communication between our VoC Feedback back-end and Cloudflare was cut.
Our system admins and operations team investigated the issue. After the root cause was determined we were able to solve the issue at 22:00 CET on Tuesday November 25th 2014. As a lesson learned we introduced further maintenance steps to detect similar issues sooner and mitigate their impact or even avoid them completely in the future.
