In general, the Comcast Business Internet Speed Test is not a recommended speed test, mainly because there is a large variation in measurement results.
- Data efficiency: 58/100
- Time to complete: 48/100
- Security: 73/100
- Privacy friendly: 30/100
- Usability: 100/100
- Accessibility: 4/100
- Informative: 50/100
With an adverstised speed of 100 Mbps and an average measured internet speed of 103.3 Mbps, we conclude that the Comcast Business Internet Speed Test is not an accurate speed test (Accuracy score: 88/100).
A miscellaneous speed test
The Comcast Business Internet Speed Test is a miscellaneous speed test. This is because the test results vary widely. In our standard test, we measured 107, 101, and 102 Mbps download speed respectively. In a number of follow-up tests, we saw that the measured speed was always different and varied from 98 to 122 Mbps.
The Comcast Business Internet Speed Test is of course owned by Comcast. The first occurence on the Wayback Machine is from April 2019.

Note that a download speed of 122 Mbps is ridiculous if you have a 100 Mbps plan. The maximum download speed we expect is
112 Mbps (with our 100 Mbps plan, this is our true internet speed).
The Comcast Business Internet Speed Test is an original speed test. However, we suspect that this speed test has the same basis as the Xfinity speed test (Xfinity is the customer brand of Comcast). The Xfinity speed test also has a huge variation in measured speeds and can measure extremely high speeds.

When to use the Comcast Business Internet Speed Test
If you just want to know what your internet speed is, then use another speed test. Read our advice for a better speed test that suits your needs.
If you want to ask Comcast Business what to do to get the advertised speed you have to test properly.
Preferably you use the speed test by Comcast (which is probably this spees test) and perform speed tests on several days.
Keep in mind that your home network is usually the bottleneck.

Tingtun was not able to test the Comcast Business Internet Speed Test.
