SUNX Update on the Service Disruption Dear SUNX Users, With regard to the service disruption that began at 23:00 (UTC+8) on 20 October 2026, SUNX hereby provides the latest progress update as follows: I. Updated Cause of the Incident According to the latest feedback from our service provider, this service interruption involves an upgrade to AWS's internal risk control system, which resulted in the suspension of the relevant cloud service account and consequently affected some of the platform's core services. Information gathered so far indicates that this interruption was not caused by a fault in the platform's own system programs. This updated explanation of the cause supersedes the preliminary assessment set out in the previous announcement. II. Services Are Gradually Being Restored At present, platform services are being gradually restored. The technical team is continuing its work on service recovery and verification, and full normal operation has not yet been achieved. SUNX has been continuously coordinating with AWS through our service provider and has requested that the matter be prioritised. As part of the recovery work still involves AWS's internal processing procedures, an accurate timeframe for full recovery cannot yet be provided. III. Next Steps SUNX will continue to follow up on progress and provide timely updates through official channels. Once the relevant services have been fully restored and verified, we will issue a restoration notice and compensation arrangements as soon as possible. We once again sincerely apologise for the impact and inconvenience caused to you by this interruption. Thank you for your understanding and patience. The SUNX Team 21 October 2026
