## Timeline of updates

- **resolved** 2024-07-25 18:30 UTC: We’ve investigated a trend of dropping email open rates for a subset of publishers since 7/25. We believe this is due to the outage with Apple’s iCloud Private Relay from 7/25 — 7/27, and that this doesn't reflect an actual change in opens.
