Resolved after 3 hours 10 minutes, affecting Whatsapp, on July 2, 2026.
### **Postmortem: WhatsApp Support Channel Instability** #### **Summary** On July 2, 2026, an instability affected our WhatsApp customer support channel. During this period, automated messages from our virtual assistant \(bot\) were not being delivered to end-users. Service was fully restored after the identification and rollback of a system change within our technology partner’s environment. #### **Impact** This incident exclusively impacted customers attempting to reach support through our WhatsApp channel. While automated messages managed by the bot failed to deliver, manual messages sent by human agents continued to operate normally. Our alternative support channels, such as email and webchat, remained fully operational and were communicated as active alternatives during the instability. #### **Root Cause** The root cause was an update deployed in the messaging service managed by our technology partner. This update introduced an incompatibility within the partner's own production environment configurations. This supplier-side infrastructure failure disrupted the automated communication flow, preventing the bot from delivering messages. #### **Resolution** Our partner's technical team investigated the issue within their environment and traced the failure back to the recently deployed update. The resolution applied by the vendor consisted of performing an immediate rollback to the previous stable version of their messaging service. Once the partner completed this rollback, message delivery was successfully restored, and our support channel returned to normal operations. #### **Lessons Learned** This incident reinforced the importance of maintaining an agile contingency and communication strategy to quickly redirect our customers to alternative channels \(such as webchat and forms\) during third-party service outages. Additionally, it highlighted the need to continuously align with our key vendors regarding the requirement for more rigorous validation and testing protocols in their own environments before promoting updates that can impact our operations.
