Our downstream providers have advised that service stability continues to improve. A small number of users on both KPN and Vodafone networks have now successfully tested and are receiving the required codes as expected.

At this time, our teams will continue validating with additional users to confirm the issue has been fully resolved. We also remain in a monitoring phase and are closely tracking the situation for any residual impact.

Identified

Our downstream providers have confirmed they identified an issue impacting one of their provider data centers, which caused a loss of connectivity to all partner‑hosted infrastructure at that location. This triggered an incident with broad, global impact across SMS‑dependent services.

As a result of mitigations already applied, significant recovery has been observed across previously affected regions, and the majority of impacted traffic has now been restored. However, full restoration is still in progress, and our providers remain closely engaged with their third‑party partners to complete recovery efforts.

Our teams will continue sharing updates as soon as new, confirmed information becomes available.

Thank you for your continued patience and understanding while this issue is being resolved.

Update

We’re still awaiting further updates from AWS and continue to actively monitor the situation. At this time, AWS is working closely with an impacted third-party data center provider following a fire incident at a NorthC data center in Almere, Netherlands, which aligns with the timing of the service disruption and may be contributing to the current impact on SMS delivery.

Early indications suggest that restoration efforts may take additional time, as infrastructure at the affected data center is being actively assessed and recovery work is ongoing, including overnight efforts as communicated by NorthC.

Our teams remain fully engaged and are closely tracking progress alongside AWS. We will share updates as soon as new, confirmed information becomes available.
