We will continue monitoring all activity.

For customers with a Segment integration, please reach out to Segment’s support team at friends@segment.com to see if your data is eligible for a manually triggered replay.
Sep 21, 17:25 EDT
Monitoring - Between 1:40 PM - 2:28 PM US/Eastern on September 21, Klaviyo API servers returned an elevated volume of 403 errors. This resulted in potential data loss from failed API calls during this window for Shopify, Recharge, and Segment integrations, as well as any direct API calls. For integrations, we will work with our partners to replay any dropped data as needed. However, any direct API calls cannot be recovered or replayed and will need to be retried.

The change that caused this outage has been reverted, and there has been no subsequent event loss as of 2:29 PM US/Eastern. We will continue to monitor error rates moving forward.
