A useful measurement report
- Include the page URL, date, time zone, browser and device.
- Describe the symptom and whether you used Wi-Fi, Ethernet, a VPN or other background traffic.
- Include the exact error, or the report downloaded after a completed test. The report’s notes are optional; remove private information before sharing.
- Explain whether the problem repeats and whether another device or connection behaves differently.
Do not send Wi-Fi passwords, router credentials, account numbers, payment information or unredacted IP addresses. The test does not need those details. A low reading alone does not establish that either your provider or this server is responsible.
Before contacting your ISP
Repeat a controlled comparison and keep failed attempts in the log. See the Wi-Fi, device or provider worksheet. For an urgent outage or billing issue, use your provider’s official support channel.
