Yes, all ISPs and server hosts are connected to the backbone.
I prefer to use Ping Test
to see what my internet looks like. It and speedtest.net are run by Ookla Net Metrics
The "ping" is how long it takes a packet of data to travel from your computer to the speedtest server, and back to your computer again.
But the pingtest measures a lot more than ping time. It also checks jitter, or how much noise is included.
Pingtest checks how many packets are lost. Lost packets are transparent to you, as lost packets are simply resent if not acknowledged on your end. Resent packets take more time and slow overall speed.
Pingtest will rate your internet grade A through F.
Bandwidth ( transfer speed ) is what is shown as download speed on speedtest.net. However the results are usually ideal conditions, so not real world results.
A better test ( though still not real world results ) would be to see what you get on pingtest.net instead of speedtest.net.
My Ping Test results. I had to use Chicago as Germantown Wisconsin was not responding.
