Subset of Scheduled SMS Delivery Failures

Incident Report for Twilio

Resolved

Scheduled messaging was degraded between 03/08/2022 13:00 Pacific Time and 03/11/2022 05:30 Pacific Time. During this period, all outbound messages scheduled for delivery more than 5 hours in the future from the time of creation were prematurely moved to Failed status. Delivery will not be reattempted. Failed messages would need to be queued for delivery again by the customer. This incident has now been resolved, and the service is functioning normally at this time.

Monitoring

Our engineers are currently investigating the customer impact of a retroactive issue with a subset of scheduled messages between 03/08/2022 and 03/11/2022. During this period, some customers who scheduled outbound messages for delivery more than 5 hours in the future from the time of creation may have seen the messages prematurely move to Failed status. We will follow up and provide customer impact details within 2 hours.
