We're making good progress on backfilling missing event data. Reporting between 12:26 PDT and 15:09 PDT on 04 Oct 2018 has been affected.

Opens and clicks for emails sent during this window may be missing location data, duplicated, and times may be up to 12 hours later than the event took place.

While some historical tracking data is still being backfilled, live tracking data is being processed, so more recent sends should see no reporting delays.

We’ve identified the cause of the tracking delays and are working on a fix to get everything caught up. Thanks for your patience!

Update: Some customers may be experiencing a delay in the processing of any A/B tests that are currently running. This is related to the current tracking issues. The A/B tests will resume once the tracking delays are completely caught up.
