INCIDENT REPORT PUBLISHED: 10/09/2026 16:00 SERVICE: Some SIP Hosted Services PEAK IMPACT: Loss of Service CONTINUOUS/INTERMITTENT (AT PEAK): Continuous PEAK PRIORITY: P1 (High Priority) DOMAIN: Internal COMMONALITY: Incident affecting specific Spitfire Hosted PBXs REPORT: On Tuesday 1st September 2026 at 09:40, Spitfire engineers identified that a number of customers using the Spitfire SIP Communicator PBX service were unable to make or receive calls. Investigation determined this to be caused by inbound traffic from a malicious party, which exhausted the available media port range on the affected servers. This prevented new calls from being established and resulted in a loss of calling functionality for impacted customers. A brief recurrence of the issue was observed the following morning as similar traffic patterns were detected. Service was restored following the identification and blocking of the offending addresses. CORRECTIVE ACTIONS: Additional security controls have since been implemented on both the PBX servers and the firewall appliances to prevent a recurrence of this issue. PERFORMANCE: In line with our Service Level Agreement, no Service Credits are available.
