We are investigating several reports from customers that are using particular ISPs that have connectivity issues to Duo. Initial details seem to stem from an issue with a peering provider that several ISPs use. We will continue to investigate and provide an update as we have more details. Duo's services continue to operate as normal assuming a stable network route. Please contact your ISP and consult their status page for updates as well.
