Zeabur Server Intermittent Offline Issue - Aliyun Singapore (ID: 69d725f8f2ab61f5dd649dfe)

Problem Description

My Zeabur server in the Aliyun Singapore region intermittently shows as offline, even though the virtual machine itself is still running. This prevents access to any projects and services on the server.

Server Information

Server ID: 69d725f8f2ab61f5dd649dfe
Server Name: Aliyun Singapore 2C 4GB
Cloud Provider: Aliyun

Current Status

isOnline: false
vmStatus: RUNNING
totalCPU: 0 (Unreadable)
usedCPU: 0 (Unreadable)
totalMemory: 0 (Unreadable)
usedMemory: 0 (Unreadable)

Specific Behavior

Server shows offline - Zeabur dashboard shows isOnline: false
VM is still running - vmStatus is RUNNING
Metrics unreadable - CPU and memory data are all 0
Projects inaccessible - Queries return "project not found or has been deleted"
Intermittent issue - Occurred multiple times in the last few hours

Affected Projects

Wordprass (WordPress + MariaDB)
n8n (n8n + PostgreSQL)

2026-04-16 12:44 - Server shows offline again
2026-04-16 12:45 - Unable to query project and service logs

Diagnostic Information

Ruled Out

✅ Insufficient resources - Previous metrics showed normal CPU/memory usage
✅ App configuration - n8n and other services were running fine before going offline
✅ Disk space - Disk usage is normal

Possible Causes

❓ Zeabur monitoring agent connection failure
❓ Network interruption between server and Zeabur control plane
❓ Aliyun network configuration issue
❓ Firewall rule changes

Request

Check the connection status between the server and the Zeabur control plane
Check Aliyun network configuration
Check monitoring agent status
Restore server online status
Ensure projects and services are accessible

Thanks for the support team's help!

Hello,

We have SSHed into your server and checked its current status:

The server is currently normal (restarted about 2 hours ago), K3s is running, and all services and system components are online. However, we noticed that all Pods have accumulated 5-14 restarts within 7 days, which confirms that the server is indeed restarting frequently, consistent with the intermittent offline issues you described.

Resource usage is currently normal (load 0.41, 2GB memory available, 23% disk usage), so this is not caused by insufficient resources.

Based on our observations, Alibaba Cloud Singapore VPS has known stability issues, which can cause intermittent network jitter or VM anomalies, leading to connection interruptions between K3s and the Zeabur control plane.

Recommendation:

If stability is important to you, we recommend migrating to a more stable provider:

Linode Tokyo or Hetzner have better stability performance.
You can use Clone Project to migrate existing projects to a new server.
After the migration is complete, delete the Alibaba Cloud server, and the fees will be refunded to your account balance.

If you wish to continue using Alibaba Cloud, you can try changing to a different region (e.g., Tokyo), but we cannot guarantee a difference in stability.

Please reply and let us know your choice.
