# Ping faster than light

I just discovered very strange thing while testing my internet connection. My ping is smaller than it should be. For example ping time to Arizona State University is about 14ms.

``````eryk@eryk-pc:~\$ ping www.asu.edu
PING www.asu.edu.cdn.cloudflare.net (104.16.51.14) 56(84) bytes of data.
64 bytes from 104.16.51.14: icmp_seq=1 ttl=60 time=13.8 ms
``````

I'm living in Poznań in Poland so my distance to Arizona State University in a straight line (very optimistic assumption) is about 10000 km. Considering the fact that ping time is a time for two directions (to the target and back to home). So my ping packet have to cross 20000 km distance. Speed of light is 300 000 km per second that is 300km per millisecond. So the smallest possible time to ping Arizona State University with my packet travelling at a speed of light is

``````20000/300=67ms
``````

I have noticed similar results for servers located in Australia and some other States of America. Is my internet connection five times faster than light?

• Underwhelming answer, but the question reminds me of the 500 mile email story which is an entertaining read; well worth your time. Jun 1, 2015 at 21:59
• @cnst because we're geeks. This is a puzzle, but when you look closer the answer is trivial. And we geeks love that kind of stuff. Jun 2, 2015 at 22:27
• @WayneWerner, A puzzle assumes that arriving at an answer is not entirely trivial; in this case, the answer, `cloudflare.net`, is already very noticeably present in the question itself!

• If you're not familiar with cloudflare, or know that it's a cdn, it's not trivial. If you don't know what a cdn is, it would also not be trivial. Jun 3, 2015 at 2:23
• Anyone can ping faster than light. `> ping ftlgame.com` I don't get what's so hard. Jun 3, 2015 at 18:08
