Resolved

The issue has been resolved after additional monitoring into the early morning. Thank you for your patience.

Updated

We are continuing to process backlogged messages. No data loss occurred.

The incident occurred between approximately 2:43 – 3:34pm CT (19:43 – 20:34 UTC). A subset of messages sent via the API during this window will experience delays while the backlog clears. Engineering is actively working to accelerate processing.

Recovering

A fix has been deployed. Messages were accepted successfully during this period and are now processing.

Investigating

We are investigating sending delay reports for some customers.
