A DNS resolution issue with the Section platform resulted in customer web applications being inaccessible to end-users. Section runs redundant DNS providers to improve total availability. Section’s platform received internal errors that corrupted platform decisions about DNS routing when communicating with the DNS provider’s API. As DNS propagated, customer web applications began to become inaccessible by end-users. Section engineering worked to correct the faulty records by successfully migrating to Section’s secondary DNS provider. The duration of the incident would have varied by customer depending on the timing of complete DNS propagation.

An internal fix has been rolled out to production.
