ITS has received several reports of individuals who have been unable to approve logins through Duo because a push or call is never received. Duo has confirmed that they are experiencing latency issues and are working to resolve them as quickly as  possible. This post will be updated as soon as the problem is resolved. If you need immediate access to a system and are seeing the Duo prompt and are finding you cannot approve your login, please contact the ITS Help Desk at 740-587-6395 so we can provide a workaround.
