Our engineers have identified the issue with a Messaging Services configuration causing consumer lag in phone number capability or status change and are working to deploy a fix. We expect to provide another update in 1 hour or as soon as more information becomes available.
We are no longer experiencing SMS delivery delays when sending messages to Multiple Networks in New Zealand via Subset of Shortcodes. This incident has been resolved.
We are resolving this incident as we found that the main cause is that some of our customers are unable to comply with the requirements from our service providers that caused the observed call failures. The next actions are for these customers to submit all the necessary configurations for them to be compliant, which is currently a work in progress.
