## Timeline of updates

- **scheduled** 2026-11-03 16:40 UTC: Tonight, Nov 3, 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. 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** 2026-11-03 20:00 UTC: The scheduled maintenance is now underway. We'll keep you updated on our progress.
- **resolved** 2026-11-04 01:02 UTC: The maintenance is now complete. That took a lot longer than expected... we are going to schedule another maintenance window starting tomorrow, November 4th at 3PM Eastern.
