6. postmortem Mar 12, 2026, 03:31 PM UTC

   On March 11, 2026, between approximately 13:20 UTC and 17:10 UTC, some devices on the emnify network experienced intermittent connectivity issues, including delayed session establishment and increased packet loss. Mitigation actions implemented by our engineering teams resulted in service progressively improving from approximately 14:45 UTC. **Incident overview** An unexpected and sudden increase in data traffic volume on one of our carrier connectivity links in the EU region exceeded the available link capacity. Despite high spare capacity built into our platform, traffic volume increased approximately sixfold within a few minutes, which the link was not dimensioned to absorb. This led to congestion on the link, resulting in packet loss that affected the ability of some devices to establish and maintain data sessions. Impacted devices experienced intermittent connectivity and may have needed to reconnect or retransmit data. **Mitigation actions taken** Our engineering team identified the source of the traffic surge and took the following actions to restore service: * Isolated the traffic that was causing the link congestion * Redirected the identified traffic to a separate, dedicated link to eliminate congestion on the primary connectivity path * Scaled up signalling processing capacity to handle the elevated request volume during recovery * Monitored the network closely as devices reconnected and traffic patterns normalized **Preventive measures** We are reviewing our link capacity planning and traffic management controls to improve our ability to absorb unexpected traffic surges without impact to customers. This includes higher capacity reserves and implementing traffic shaping mechanisms to better protect shared infrastructure.
