As the internet is a large, sometimes unpredictable network, not all issues that may occur are in our control. If a performance issue occurs and does not get resolved by our automatic systems, action may be required. Below you can find how you should report network performance issues.

Step 1: Pre-Checklist for Server-Related Issues

To ensure a fast resolution and rule out common local configuration issues, please verify the following on your server before creating a support ticket:

  • LACP Configuration: Confirm if your server is configured to use LACP. If you are unsure, please use our guides to ensure your setup is correct.

  • Hashing Mode: Verify that hashing is set to the Layer3+4 mode.

  • Port Negotiation: Check that both network ports have successfully negotiated their connection.

  • Multi-Stream Testing: If using multiple streams to test your connection, confirm they are correctly balanced and utilizing both ports.

  • Link Congestion: Ensure the server's network link is not already congested by other traffic outside of the test you are running.

  • Remote Server Capacity: Verify that the server you are testing to/from has enough network and processing capacity to handle the test at the full speed of your server's connection.

  • Official Speedtest Tool: If you are using the Ookla speedtest, you must use the official command-line tool. You can find the correct tool for your operating system here.

Step 2: Information to Include in Your Support Ticket

When you submit a support ticket, providing the following information is essential for our network engineers to begin their investigation:

  • Server Tag: The unique tag of the affected server (e.g., 123-456).

  • Evidence of the Issue: The specific data and output you used to conclude there is a performance issue. Please include the actual, unedited information for our team to review.

  • Remote Server IP Address: If applicable, the IP address of the remote server that was used for testing.

  • Link Status Command Output: The complete output of the following shell command: ip -s link
