Gigabit ISPs: Real World Usage vs. Speed Tests

One of the things I talked about recently in my Gigabit Pro update video is that even though you have the bandwidth you likely will never make full use of it on any single task.

Sure it’s possible to run a speed test to fully saturate the connection as I have done many times, but when doing real world tasks things work differently. So even though I have a full six gigabits available, I’m usually only getting about half a gigabit to each location I’m sending data to.

The image above was taken from my Unifi app as I was uploading an 8.7 GB video to YouTube and Floatplane simultaneously. Each can only take about 500-600 megabits per second.

Remember the Internet is not one network. So it’s possible that within Comcast’s infrastructure I can utilize the full bandwidth. But once we cross outside the network it depends on how different networks interoperate and what kinds of bandwidth they allow across those crossing points. In some cases there are multiple networks to traverse!

Starlink Holding Up Against Russian Cyberattacks

Starlink has become a key communication tool for the Ukrainian military and the Russians are having a hard time detecting and jamming it. As we’ve found in our Starlink coverage the service is remarkably easy to connect to and offers bandwidth on par with low to mid range cable Internet services.

Elon Musk in a tweet today says that the satellite network has so far resisted Russian jamming and hacking attempts. Starlink’s network engineers are up against a tough adversary with state level resources so they no doubt will have to remain on their toes.

The service doesn’t work as well in the eastern part of the country as the satellite network still relies on ground stations to connect users to the Internet. But SpaceX is working on a laser based orbital relay that would bypass many ground stations to route traffic. At some point we might see SpaceX launch servers into positions to act as CDNs for streaming services, etc.
