Lightsail network disconnected while using as a tunnel after June 28th


Lightsail network disconnected while using as a tunnel after June 28th

What happened to AWS lightsail after June 28th 2022? I use lightsail mainly for learning and development purpose, meanwhile using as a tunnel to connect to other sites. From Jun 28th, seems there is a new network throttling is implemented. The traffic starts to get blocked after a certain period of time while the network usage is high. Previously there is no behavior like this. Meanwhile, I can see the CPU credits are not used up. Did you see similar issue on your instance? Or any ideas to further troubleshooting?

Hi, If your AWS Lightsail instance is experiencing network connectivity issues and you've ruled out CPU credits as a potential issue, you can try to troubleshoot using these steps:

  1. Check Logs and Monitoring:
    • Review the instance's system logs, application logs, and any monitoring metrics to identify any anomalies or errors that might be causing the network connectivity issues.
  2. Networking:
    • Check that the instance's networking settings are correctly configured, this includes security groups, firewall settings, and network ACLs.
  3. Analyze traffic:
    • Use network monitoring tools to analyze the incoming and outgoing network traffic to identify any unusual patterns or spikes that might be causing the connectivity problems.
  4. Resource Utilization:
    • While you have checked CPU usage, also monitor memory and disk usage. High memory or disk usage could potentially impact network performance.
  5. Check for Updates:
    • Ensure that your instance's operating system, software, and applications are up to date with the latest patches and updates.
  6. Network Throughput Limits:
    • AWS Lightsail instances have predefined network throughput limits based on the instance plan. Make sure you are not exceeding these limits during periods of high network usage.
  7. Instance Size:
    • Consider upgrading to a higher instance size with better network performance.
  8. Test Connectivity:
    • Test the network connectivity to different sites from your Lightsail instance using tools like ping, traceroute, or other network testing tools.

Remember to do these steps one at a time and test after each change to see if the issue improves. This will help you narrow down the root cause and find an effective solution. Hope this helps!
