Hi there,

The traceroute results you provided show the path that a packet of data takes from your computer to the destination server (in this case, domain.com). Each line of the traceroute represents a “hop” or step along that path. When you see a line with “* * * Request timed out”, it means that a particular step didn’t respond in a timely manner.

In your case, it looks like the packet successfully made its way to the destination server (last hop), despite the time outs in hops 6 to 10. These timed out hops might belong to networks that either have ICMP blocked or have firewall rules that are dropping the ICMP echo requests, which are needed for traceroute. This is a common security measure and doesn’t necessarily indicate a problem.

If you’re not experiencing any issues (slow connections, intermittent connectivity, etc.), then there’s likely nothing to worry about.

However, if you’re experiencing issues with reaching the domain or the domain’s services:

  1. Check if you can reach the domain via a web browser, or if it’s a specific service, test the service.
  2. Reach out to your Internet Service Provider (ISP) with these traceroute results, as they might be able to provide more insight into the timeouts and any potential issues on the path to the server.
  3. Since you mentioned routing through Cloudflare, check the Cloudflare dashboard for any reported issues. Cloudflare’s support might also be able to provide guidance based on the traceroute results.

A few timeouts in a traceroute do not necessarily indicate a problem, especially if you can still reach the destination server successfully.

Best,

Bobby
