Control D operates on top of an anycast network, so your traffic should be routed to the closest server location under normal circumstances. However, nothing is perfect, so in order for us to troubleshoot performance issues, we need the following:

  1. Results from the Status page (use the purple Copy Results button)
  2. Traceroute (instructions below)
  3. Take the data and email it to [email protected], along with:
    1. Network Type [Residential / Work / School / Other (please specify)]:
    2. Network Architecture [Fiber / Cable / DSL / Wireless Broadband (5G-powered "Airfiber" falls under this category) / Cellular / Satellite / Other (please specify)]:
    3. Brief overview of issue
    4. Is there different behavior at different times of day? Please provide a traceroute from both times if so

Status Page

On the device that is experiencing the issue, navigate to the Status Page (https://controld.com/status), and press the "Copy Results" button. It will look something like this (when you paste it)

Traceroute

Please copy and paste the results of the traceroutes rather than sending a screenshot for faster resolution.

  • For DNS related troubleshooting, trace: dns.controld.com
  • For proxy related troubleshooting: trace: proxy-latency.controld.com

Windows

Go to Start, search for “cmd” and open the Command Prompt. Enter this command: tracert dns.controld.com (or the other hostname)

You should see something like this:

C:\>tracert dns.controld.com

Linux

Open Terminal. Enter this command: sudo mtr -w -z --show-ips --report-cycles=10 dns.controld.com

You should see something like this:
