Update -
The issue where we were seeing a small drop in Delivery Receipts (DLRs) for SMS messages appears to have been resolved at 20:16 AEST (10:16 UTC) 19-May-2022
We have seen the percentage of DLRs returned for outbound SMS to mobiles remain within normal ranges for the last 10 hours.
Note: some messages will legitimately stay in a pending state for 24 hours or more while the carrier continues to reattempt delivery to a mobile that is unreachable (e.g. a mobile that is turned off or out of reach of the mobile network)
To ensure this issue is fully resolved we will continue to monitor the percentage of DLRs returned through the Australian morning as traffic ramps up for the new day.
Please note the majority of messages did get their DLR as usual throughout this incident. Delivery of messages to mobiles has remained at normal levels throughout, the issue was a lack of DLR to confirm that delivery, there should have been no impact to mobile users who will have received their SMS messages as normal.
If you are still experiencing issues please contact support.
