I also use internet speed test.  Their ping numbers are useless, because
their OOKLA servers are chosen geographically, not by routing distance.
If packets are going between ComCan't and FrontRear, for example, they
pass through Seattle (probably) or Oakland (maybe) and half a dozen
switches, even if they are going to your next door neighbor (on a
different service).  If the packets go through the same fiber switch,
to other customers using the same service in the same area, you are
mostly seeing packet queueing delay through the switch, very small. 

For ping times, I use linux ping(8).  When I want details of the path
the packets take, I use linux traceroute(8).  The latter can be messy,
because packets can take many routes from here to there.

For your amusement, here is the traceroute from my Beaverton laptop to 
dicksteffens.com in Phoenix AZ (XX = redacted):

Here is the traceroute from my wife's Portland desktop to my Beaverton router,
which actually takes longer because DSL is so slow:
