Summary
On 14 May 2026 between 13:26 and 14:09 UTC, the Messaging API experienced a service disruption lasting approximately 43 minutes. During this window, customers may have experienced timeouts or errors when sending messages or making API calls to waba-v2.360dialog.io. Service was fully restored at 14:09 UTC.

Timeline (UTC)
13:26 – Service disruption begins.
14:09 – Service fully restored.

Root Cause
An infrastructure update did not behave as expected under production load. The new configuration was unable to sustain the volume of customer traffic, which led to the temporary disruption.

Resolution
Once the issue was confirmed, our engineering team applied a mitigation that restored the previous configuration. The Messaging API recovered immediately after the mitigation was in place, and we have continued to monitor the platform closely since the incident.

Preventive Measures
To reduce the likelihood and impact of similar incidents in the future, we are strengthening our infrastructure change process. This includes expanded validation prior to production rollout, more granular runtime monitoring on critical components, and a more gradual approach to applying production traffic changes.

We apologize for the disruption and any impact this may have had on your operations. We take the reliability of our platform seriously and are committed to learning from this incident.

The issue is now resolved.

The issue is now resolved as we have received the following update from Meta:

Meta has recovered from an earlier outage impacting Embedded Signup, and services have now been restored. We apologize for any inconvenience that this may have caused.

We are closely monitoring the situation and awaiting updates from Meta regarding the deployment of the fix.
