Update - The underlying issue causing analytics delays has been fixed, and the single job processing events for the impacted metrics has been split into two separate jobs in order to better handle the required workload moving forward. However, both new jobs will be in the process of bootstrapping for several more hours.

At this time, analytics for the 12.5% of metrics impacted are still delayed, and campaign, flow, and dashboard reports may appear unpopulated or outdated as of 12:00 AM (US Eastern Time) on Sept. 16. We will provide further updates once we are able to begin catching up analytics for all impacted metrics.

Identified - We have identified an issue impacting roughly 12.5% of all Klaviyo metrics. Campaign, flow, and dashboard reports may appear unpopulated or outdated since 12:00 AM (US Eastern Time) on Sept. 16 for impacted metrics. Campaign sending, flow-triggering and real-time segmentation are not impacted, and no data is lost. We will provide updates as metrics catch up.

Sep 14, 2021
Completed - Scheduled maintenance is complete.
Sep 14, 01:14 EDT
In progress - Scheduled maintenance has begun.
Sep 14, 00:56 EDT
Scheduled - Beginning at 1:00 AM (US Eastern Time) on Tuesday, September 14, 2021, Klaviyo's Engineering team will be performing maintenance on our flows database.

We expect the maintenance period to last approximately 15 minutes. During this time, users will not be able to load or modify flows, dashboards, analytics, benchmarks, or create and view SMS campaigns. Flow sending will also be paused during this window but will resume upon the completion of the maintenance window. Any flows that weren’t sent during the maintenance window will be sent retroactively.

Thank you for your patience.

Completed - All instances of over-counting have been repaired. This maintenance window is complete.
Sep 12, 23:22 EDT
Update - All analytics are now real-time. A small percentage of metrics will display minor over-counting from approximately 12:00 PM - 2:00 PM (US Eastern Time) on Friday, September 3. We will keep this maintenance window in "verifying" status until these metrics have been repaired.
Sep 6, 11:09 EDT
Update - Analytics are now real-time for approximately 60% of all metrics. Analytics for all remaining metrics are still several hours behind, but we expect that they will catch up within the next 24 hours. We will post further updates as soon as they become available.
Sep 5, 23:23 EDT
Update - Issues with downstream systems prevented analytics jobs from processing events at the desired rate today. As a result, analytics are still several hours behind in most cases. We will post further updates as soon as they become available.
Sep 4, 21:41 EDT
Update - Analytics are catching up but are still several hours behind in most cases. We will provide another update as soon as we have a better estimate as to when analytics will be real-time.
Sep 4, 00:32 EDT
Update - Issues with downstream systems were encountered overnight as our analytics processing infrastructure was catching up to real-time. As a result, all analytics delays will persist throughout the course of the day. We will post further updates as soon as they become available.
Sep 3, 08:38 EDT
Verifying - The scheduled maintenance has finished, but analytics delays may persist as our event processing infrastructure catches up to real-time. We believe all analytics will be back to real-time in approximately 3-4 hours, and will post further updates once all delays have been resolved.
Sep 3, 00:09 EDT
In progress - Scheduled maintenance is in currently progress. We will provide updates as soon as they become available.
Sep 2, 17:27 EDT
Scheduled - Beginning at 5:30 PM (US Eastern Time) on Thursday, September 2, 2021, Klaviyo's Engineering team will be performing maintenance on our event processing infrastructure.

We expect the maintenance period to last approximately 4-5 hours. During this time, all analytics, including Campaign reports, Flow reports & Custom Analytics reports will appear outdated. However, segmentation, flow triggering and campaign sending will not be impacted.
