We are performing a planned migration of SMS traffic nodes to new infrastructure. This activity is part of a hardware expansion project.
Read More - Expected Impact
SMS traffic and API connections may be interrupted for up to 1 hour. Existing SMS connections may disconnect and fail until services are restored.
We recommend migrating SMS connections to the alternative cluster before the maintenance window.
Avoid running SMS campaigns during the maintenance window to minimize delivery delays.
The alternative SMS cluster will remain fully operational and unaffected.
