Identified
While we've observed noticeable recovery after the implementation of the workaround, we continue to see intermittent delivery delays sending and receiving Toll Free SMS and MMS messages in US and Canada, along with a small subset of T-mobile traffic on US long codes. The issue is also causing delivery receipts to be delayed, with delivery status stuck at "Sent". Our engineering team is continuing to work with our carrier partner to fully resolve the issue. We will provide another update in 1 hour or as soon as more information becomes available.

Update
We are now observing some recovery in which some SMS and MMS to/from US and Canada networks from US Toll-Free and US long codes are being delivered. Our engineers have identified the issue and implemented a workaround for older messages. However, message DLRs will continue to be delayed even while messages are getting delivered. Our engineers are continuing to work with our carrier partner to resolve the issue. We will provide another update in 4 hours or as soon as more information becomes available. (from upstream)
