Dear customer, dear partner,
On 3 September 2026, a service degradation affected part of our production infrastructure.
The primary issue occurred on node 188.66.8.22 (BRU), where an internal process entered an abnormal state, causing a significant increase in system load and the loss of active SIP registrations. As a result, some customers may have experienced temporary loss of SIP registration, delayed call setup or intermittent call failures.
The issue was caused by an internal process becoming stuck in an unhealthy state and failing to recover automatically. The resulting system load affected SIP signalling and registration handling.
The unhealthy process was cleared and services recovered at approximately 6.15 pm. System load and SIP registration handling subsequently returned to normal.
Following the incident, we are reviewing monitoring and alerting for abnormal system load, SIP registration levels and process recovery mechanisms.
We sincerely apologize for any inconvenience caused by this incident and continue to closely monitor the platform.
Best regards;
SEWAN technical team
