Update (Sept 12, 1:20 p.m.): The issue has now been resolved. Users should be able to continue using SMS to authenticate 2FA challenges.
What is happening? Duo two-factor authentication (2FA) is investigating an issue causing SMS delivery issues and are working to correct the issue as soon as possible.
What is the impact? If an individual chooses to receive a 2FA challenge via SMS text, they will receive a successful confirmation message from Duo, but the codes will not have been sent.
Alternative to SMS challenge: Individuals can choose to receive a 2FA challenge via the “Call me” option until the issue has been resolved.
IST will send an update when more information is known, or when the issue has been resolved. Thank you for your patience.
