Question

I am having trouble reaching my website http://example.com/ from different networks. Are your nameservers working properly?

Answer:

Hello,

Thank you for reaching out to Cloudflare Support.

Cloudflare's nameservers are functioning properly as expected. However, this issue may be attributed to factors beyond Cloudflare's nameservers, such as network routing issues and DNS misconfigurations.

Are there any error messages when you visit your website?

Thought Process:

First, I've checked if Cloudflare Services are functioning as expected using Cloudflare Status or if there is any ongoing maintenance. The customer mentions experiencing issues from different networks, so it's likely a specific configuration or network-related issue. By requesting any error messages from the customer, I can investigate further and provide more targeted assistance. Additionally, I've provided a detailed link with some common errors for further investigation.

Tools:

DNS Tools: Like DNS Checker to verify DNS records and propagation status globally.

Command-line tools: Such as dig and nslookup to check if the domain resolves to the correct IP address from different networks, and Ping and Traceroute to identify any network routing issues that might be affecting the website's accessibility.
