Service Disruption Notification - MNS Partner Carrier Connectivity Incident (GNOC-3024)

We have been closely monitoring since the corrective action was taken, and have observed no additional impacts. We are considering this issue resolved at this time.

We continue to observe and receive customer confirmation of service improvement. AT&T discovered and corrected an issue introduced with the May 31st change activity. We are currently monitoring to ensure stability. We will consider this resolved if no further impacts are observed after one hour.

We have seen improvement with test devices. We are now working on the restoral of the customer devices and continue to monitor for full recovery.

The workaround was not successful. AT&T is preparing to swing the traffic back to the primary gateway and roll back the changes that were implemented on May 31st.

AT&T has completed the workaround. Devices are now establishing data sessions on the secondary gateway. We are monitoring to confirm service improvement.

AT&T has reported there was a temporary hold placed on the workaround because they found something in the core network that might be related to the issue. ETR is approximately 15 minutes.

AT&T is moving the data traffic to a secondary gateway for the workaround. Preliminary work is complete but the final activity is still ongoing. We will provide further updates as they become available.

Implementation of the workaround is ongoing. The activity is expected to be completed within the next 30 minutes.

The AT&T engineers have initiated the implementation of the workaround. ETR is approximately one hour.
