Detection and Impact:  On January 14th at 9:22AM PT Okta internal monitoring alerts indicated errors in loading custom domains in OK Cell 8.  During this time customers who utilize customized domains in OK Cell 8 experienced errors accessing the service.    Root Cause Summary:  In order to resolve an issue which was caught by our internal monitoring during a change the previous evening, Okta engineering staff was redeploying the edge servers. Due to a bug in the operating procedure used, the service became momentarily unavailable until corrective actions were taken to fully restore the service.    Remediation Steps:  At 9:24AM PT, Okta Engineering quickly identified the issue and resolved it by placing healthy servers in service.    Preventative Actions:  Okta has updated the operating procedure and improved the tooling used for managing custom domain services. To ensure this does not happen again, Okta is enhancing current automated testing of this process.
