Substack: Dropping email open rates due to Apple iCloud Private Relay outage
Timeline of updates
- resolved
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.
From Substack’s published incident history: for incidents before Rewindex began polling this status page, only the final update text is available.
Archive proof
Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert.
How the archive is checked, and what it cannot prove.
This incident predates live tracking (October 17, 2026). It came from the vendor’s own published history, which is not covered by checkpoints.
Impact, status and times are the vendor’s own, as last archived. View on substack.statuspage.io (opens in new tab).
