Campaign and flow page loading errors
Resolved - Analytics processing for campaigns and flows is fully caught up and operating normally. We appreciate your patience throughout this incident. This incident has been resolved.
May 8, 20:31 EDT
Monitoring - Analytics processing for campaigns and flows is recovering and the delay is decreasing. Sending, scheduling, and other core functions remain fully operational. We're monitoring closely and will confirm once analytics return to normal operation.
May 8, 19:13 EDT
Update - Sending, scheduling, and other core functions are operating normally. Analytics for campaigns and flows are currently delayed by approximately 2 hours. These issues are tied to instability with an upstream infrastructure provider (AWS) and we are continuing to work through them. We'll provide updates as soon as we have more to share.
May 8, 16:19 EDT
Update - System performance is improving, and users can now access campaigns pages to complete scheduling. We determined these errors resulted from a combination of instability with an upstream infrastructure provider (AWS) and a significant increase in retry traffic. We continue to monitor closely and appreciate your patience throughout this incident.
May 8, 14:37 EDT
Identified - We have identified the root cause of the errors and our engineering team is actively working toward a resolution. We'll provide updates as soon as more information is available.
May 8, 13:10 EDT
Investigating - We are currently investigating reports of errors loading campaign and flow pages within Klaviyo. Campaign and flow sending is not impacted. Our engineering team is actively working to identify and resolve the issue. We'll provide updates as soon as more information is available.
May 8, 11:02 EDT
Processing delays
Resolved - Segmentation continues to process in real-time and is fully recovered. We determined the delays resulted from instability with an upstream infrastructure provider (AWS). This incident is now resolved.
May 8, 15:05 EDT
Monitoring - Segmentation has been restored to real-time processing, and campaign and forms analytics have now recovered. This was a reporting UI display issue only, no data was lost. Our engineering team continues to monitor closely until our upstream service provider has confirmed full recovery.
May 8, 12:59 EDT
Update - Segmentation has been restored to realtime processing. Our engineering team continues to restore the remaining affected analytics. We will continue to provide updates as real-time analytics functionality resumes.
May 8, 03:08 EDT
Update - A subset of customers are currently experiencing segmentation processing delays of approximately 1.5 hours and may find that analytics data is not fully up to date. Access to reporting pages has been restored and our engineering team is actively working to bring segmentation and analytics back to real time. We'll provide updates as soon as more information is available.
May 7, 23:46 EDT
Identified - Our engineering team continues to investigate areas affected by an upstream service provider. Customers may experience processing delays for segmentation and analytics, and loading issues with reporting pages.

For campaigns, sends may not reach the most up-to-date audience due to segmentation delays. Segment-triggered flows may also fail to trigger correctly as profiles may not be added to or removed from segments as expected. We'll provide updates as soon as more information is available.
May 7, 22:22 EDT
Investigating - We are currently investigating an issue affecting analytics and reporting, flows, campaigns, and segmentation. This issue appears to be related to a disruption with an upstream service provider. Customers may experience errors or be unable to load flows and campaigns pages, see delays in real-time segmentation updates, and find analytics data temporarily unavailable.

Our team is actively working to resolve this. We'll provide updates as soon as more information is available.

May 6, 11:59 EDT
Update - Access to klaviyo.com and core platform services has been restored.
