I’ve used the internet daily for years, but this week, I finally got a glimpse of how data actually travels behind the scenes. Using ping and traceroute commands on my Mac, I tested how packets move from my device to websites in the U.S., Japan, and Mexico. I wasn’t expecting it to be this interesting, or this eye-opening.
Sites I Tested
To see how distance affects performance, I picked three sites from different regions:
Google.com (United States)
Rakuten.co.jp (Japan)
MercadoLibre.com.mx (Mexico)
Ping Results: Speed Check!
Ping sends a tiny packet of data to the target server and waits to see how long it takes to get a reply. Here’s what I got:
| Website | Avg Round-Trip Time | Packet Loss |
|---|---|---|
| Google.com | ~29 ms | 0% |
| MercadoLibre.com.mx | ~30 ms | 0% |
| Rakuten.co.jp | ~141 ms | 4% |
Not surprisingly, Rakuten (based in Japan) took the longest. That 4% packet loss might not seem like much, but even small losses can impact apps like video calls or streaming, where smooth, uninterrupted data is key.
Traceroute Results: The Journey Itself
Traceroute breaks down the exact path the data took. Each “hop” is a router or node between me and the website.
Google.com: ~8 hops through U.S.-based routers — fast and smooth.
MercadoLibre: 9 hops, but it timed out at the end.
Rakuten: 8 hops, with some noticeable latency spikes near the final destination.
Those timeouts in traceroute aren’t always errors, they often happen when routers are configured to block ICMP packets, which is what traceroute uses. This is done for security reasons, to avoid exposing internal network details or overwhelming devices with diagnostic traffic.
Why Ping and Traceroute Matter
These tools are more than just cool, they’re practical. Here’s how:
Ping tells me if I can reach a site and how fast it responds.
Traceroute helps find out where the delay or failure is happening, whether it’s my router, my internet provider, or something overseas.
If ping fails, maybe the server is down or my device isn’t online. If traceroute fails partway, maybe a firewall is blocking it or the path is overloaded.
Real-World Troubleshooting Examples
Gaming server too laggy? Check the route with traceroute, maybe it’s not you.
Video call keeps dropping? Ping the service to see if there’s packet loss.
Can’t load a site at all? Traceroute might show the signal’s dying at hop #3, maybe a local network issue.
Final Thoughts
This assignment gave me a new appreciation for what’s really happening when I load a website. The internet isn’t just “on," it’s made of routers, pathways, and rules, all working together. Seeing that in action, and learning to troubleshoot it, was empowering.
These tools aren’t just for IT pros. Anyone can use them to diagnose slow connections, fix Wi-Fi issues, or even just learn something new about how the web works.
