Past Incidents
Oct 1, 2016

No incidents reported today.

Sep 30, 2016
Resolved - We've confirmed that authentications are all completing with normal latency, and that the issue has been resolved.
Sep 30, 16:46 EDT
Update - Authentication latency is still maintaining normal levels. We are still closely monitoring to ensure that no new authentication issues are observed.
Sep 30, 14:58 EDT
Update - Authentication latency has returned to normal levels, but we are still actively monitoring the situation, and will provide another update in 30 minutes or less.
Sep 30, 14:22 EDT
Update - Authentications are showing an increase in latency again. We are continuing to take corrective measures and will provide another update in 30 minutes.
Sep 30, 14:05 EDT
Monitoring - From approximately 17:00 to 17:30 UTC, we saw a large jump in latency on DUO-40 - we’ve provisioned more capacity and are monitoring the situation. Some authentication attempts during that time took several seconds, when they usually take less than one second. Most authentications are returning to normal, but some are still taking several seconds. Next update in 30 minutes.

No incidents reported.

Sep 28, 2016
Completed - The scheduled maintenance has been completed.
Sep 28, 00:01 EDT
Update - The IP address change has been completed. Integration hostnames will now resolve to new IP addresses in the 52.59.243.192/26 range. The old IP address range will continue to respond to traffic for the next two weeks. After September 28th at approximately 4pm EDT, the old IP address will be decommissioned and will no longer respond to traffic. If your firewall is explicitly whitelisting Duo Security, please verify that the new IP address range is included to ensure a seamless transition.

Another notice will be sent when this final change is initiated and complete on September 28th.
Sep 14, 18:55 EDT
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 14, 00:01 EDT
Scheduled - As we expand our infrastructure, we are transitioning integrations on DUO38 to a new IP range. Starting Wednesday, September 14, 2016, your integration hostnames will resolve to new IP addresses in the 52.59.243.192/26 range. The current IP address range will continue to respond to traffic for the two following weeks.

On September 28, 2016, Duo will remove current IP addresses from our systems, leaving only the new IP range. If your firewall is explicitly whitelisting Duo Security, please verify that the new IP address range is included to ensure a seamless transition.

If you have any questions regarding this change please contact our technical support department for further assistance.

No incidents reported.

Sep 26, 2016
Resolved - We have confirmed with Amazon's support that Amazon Web Services have resolved the networking issue and SMS and phone call delivery via all providers is restored as a result.
Sep 26, 13:27 EDT
Monitoring - We identified elevated outbound telephony (SMS and voice) failure rates between 7:38 AM and 8:14 AM Eastern on 2016-09-26. We believe the failures were related to an Amazon Web Services networking issue affecting a subset of our multiple telephony providers. The issue appears to have subsided and we are continuing to monitor for additional failures.
