Postmark: Scheduled maintenance: search and data upgrade (continued)
Timeline of updates
- scheduled
Part two of our search and data upgrade! Starting at 3:00 PM EST (20:00 UTC), we’re upgrading the system that powers activity, stats, and message details. We expect it to take 4 to 10 hours.
What to expect:
- Sending should continue as normal.
- Activity, stats, message details, and webhooks may be slow, delayed, or briefly unavailable.
- You may see a short blip when we switch over to the upgraded system.
Once again, you don’t need to do anything. If a webhook or API call fails during this window, retry it a bit later. We’ll post updates here as we go.
- in progress
The scheduled maintenance is now underway. We'll keep you updated on our progress.
- resolved
The maintenance is now complete. Thanks for your patience.

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. That proves these records existed by then and have not been changed since, by anyone, Rewindex included.
How the archive is checked, and what it cannot prove.
