Resolved Feature Disruption

This incident has been resolved.

Between 7:13am - 7:43am PDT and 8:22am - 9:30am PDT, Okta observed a noticeable increase in the volume of SMS retries across all Cells except US Cell 3. An increase in the volume of SMS retries indicates delays in SMS message delivery for customers. As such, customers leveraging SMS for Multifactor Authentication or Account Recovery may not have received the SMS message and would have been prompted to retry. Upon retry, automated fail-over to Okta's other SMS vendor occurred and SMS responses were successfully delivered which minimized impact. All other authentication factors, such as Okta Verify, Voice call, Duo, Yubikey, Google Authenticator, or Security Question were not affected.
