Analytics Events Processing Delays
Resolved - As of 10:10 pm Eastern Time on Oct 8th, all delayed analytics have been processed and new analytics are processing in real time. This incident is now resolved.
Oct 8, 22:16 EDT
Monitoring - Delays have now largely cleared. We continue to monitor closely and will share another update shortly.
Oct 8, 22:09 EDT
Update - Delays in analytics events have increased and now reach up to 1 hour and 45 minutes for all customers. Segments that rely on these events may not be up to date while our Engineering team actively processes the backlog. Campaign and flow sending, along with open and click events, remain unaffected. We are working to resolve this as quickly as possible and will share another update shortly.
Oct 8, 21:21 EDT
Identified - All customers are experiencing delays of up to an hour in analytics events, so Sent and Delivered reporting and received profile events may temporarily appear missing. Campaign and flow sending, along with open and click events, are not affected. We have identified the cause of the delays. We are working to resolve this as quickly as possible and will share another update shortly.
Oct 8, 20:10 EDT

Oct 8, 12:06 EDT
Identified - The issue has been identified and a fix is being implemented.
Oct 8, 11:49 EDT
Update - We are continuing to investigate issues preventing some customers from logging in to Klaviyo or loading pages in the app. We have not seen any impact to campaign or flow sending. We will share another update as soon as we have more information.
Oct 8, 11:29 EDT
Investigating - We are investigating reports that some customers are unable to log in to Klaviyo or are seeing pages load slowly or not at all. Our team is actively working to restore normal access. We will share another update as soon as we have more information.
