From approximately 9:56 PM to 10:06 PM UTC, due to an incorrectly applied DNS change made to the duosecurity.com zone, some customers hosted on DUO1 may have been unable to contact their Duo admin panel, API endpoints, or other aspects of the service between these times. Our operations team has acted quickly to resolve the issue, and customers have confirmed successful resolution of their API hostname addresses, as well as successful authentication. If you're still seeing an issue, please try flushing your DNS cache and try again.
