We are currently experiencing disruptions with socket connections in AP1 cluster, which began at 10:00 UTC. Clients may experience reconnections. Our team is actively investigating the issue and working to restore full connectivity as quickly as possible.

A fix is implemented. We are seeing improvements and continue to actively monitor the situation to ensure full stability. During the incident, many clients successfully connected using fallback protocols.

We observed unusual activity on the cluster, likely caused by at least one customer experiencing a cyber attack. Our team is mitigating the issue while simultaneously increasing cluster resources to minimize impact on other customers. The cluster availability is returning to normal. We continue to monitor closely.
