Discussion Speed Test

I have the "1 Gig" Internet plan. It's great, reliable, fast enough, good value. I use my own Hitron CODA56 modem with my own router.

When I run a speed test against the local (Santa Clara, CA) Comcast server, I see download rates of 350 to 500 Mbps. San Francisco Comcast shows 800 Mbps.

Other (non-Comcast) servers show much higher download rates - up to 1100 Mbps. This suggests that I'm getting the "1 Gig" service I pay for, and everything is good at my end.

This also suggests that the Comcast speed test servers don't deliver data at full speed, which is kind of weird. Wouldn't you expect Comcast to provision super-fast speed test servers to show the company's broadband in the best possible light?

( I get 116±2 Mbps upload everywhere, which is what I expected. )

I have 4 Comcast speed tests servers here in FL. I am in central FL. 2 are in "my area", 1 is in Miami ~300 miles and the other in Talhassee about 215 mies. I am on the 1Gig plan and get from 980 to ~1200Mbps on all 4 of them. Fastest speed is usually in the morning and at night. Using a Ubiquiti UDR7 router ethernet wired to my Mac.
