Twilio Conversations was degraded for 8 minutes between 22:44 and 22:52 Pacific Time on 03/26/2026. During this period of time customers may have experienced error 5xx for their API getListMessages requests. The issue has now been resolved.
The incident has been resolved and SMS delivery from a subset of Twilio Long Codes and Alphanumeric Sender ID to MobiFone network subscribers in Vietnam is operating normally.
We have fully investigated the Twilio Accounts not reactivating after successfully adding funds to the Account issue, and it was determined that the impact was limited to a small set of customers, who have been contacted individually to address any concerns. All systems are operational.
