Instruments to Locate Your Server
The superior news is you do not have to have a tremendous accurate test, in its place, a rather accurate resolution is readily readily available. All you have to have is a minimal knowledge of the velocity of mild and optical fiber! Key items of information:
1. Light travels at approximately 186,000 miles for each 2nd or 186 miles for each millisecond in a vacuum.
two. Fiber has a refractive index of around 1.46.
three. The present day “Internet” is fiber when dealing with long distances.
In scenario you have not discovered, these are not actual calculations.
The future stage in your finding out system is to have an understanding of a “ping” test. You probably have the “ping” tool on your computer by now. “Ping” is a basic system utilised to check out community connectivity and effectiveness. It will ship a test packet of information out to a specified domain or IP and time how long it takes for that domain or IP to react. It will report that back again to you in “milliseconds.” We have instructions if you have by no means utilised this in advance of.
Soon after you have accomplished the ping assessments, just take the the resultant milliseconds and multiply it by the velocity of mild in fiber. This will give you the round trip mileage. Divide by two for the one way distance:
Taken from the typical result of the Linux illustration from earlier mentioned for a ping from Newark, Delaware to Los Angeles, California
77.two Milliseconds * 186 miles for each millisecond / 1.46 refractive index = 9835 miles round trip or 4918 one way.
Wait around a millisecond, touring from Newark, DE to Los Angeles, CA is not almost 5000 miles! Straight line distance is about two,350 miles. The shortest distance by motor vehicle from Google is 2700 miles. In this scenario, mainly because we have a superior strategy of what towns the actual physical route goes by way of, it is about three,two hundred miles. So what provides?
There are a bunch of outside the house components that impact the “distance”:
1. The test packet have to be encoded and decoded by your computer and the goal computer.
two. Equipment like switches and routers (test a “trace route“) have to interact with your packet to get it to it is desired destination.
three. Not all of the route will be about fiber. Most of it will be, but particular parts these types of as your have Internet relationship, will not be.
four. Daily life isn’t perfect.
Try out It Yourself
On the other hand, this is a truthful way to examine “distances” to track down your server site. Try out it out on different sites and examine it to to our East Coastline info center (suburban Washington, D.C.) and our West Coastline info center (Los Angeles, California). Ping the following to see the distinction:
