Upload Speed

The rate at which data travels from your device to the internet, measured in Mbps. Critical for video calls, cloud backups, live streaming, and working from home.

What It Means

Upload speed was historically treated as an afterthought by cable ISPs, which designed DOCSIS 3.0 networks with 10:1 downstream-to-upstream ratios. A 1,000 Mbps Xfinity or Spectrum cable plan typically offered only 35 Mbps upload, sufficient for web browsing but painful for professional Zoom calls, Backblaze cloud backups, Twitch streaming, or YouTube content uploads. The COVID-19 remote work shift in 2020 made upload asymmetry a political issue, the FCC raised the broadband upload benchmark from 3 Mbps to 20 Mbps in March 2024, a 6.7x increase, and set a long-term aspirational target of 500 Mbps upload. Fiber remains the only widely available residential technology delivering true symmetrical speeds out of the box, AT&T Fiber and Google Fiber offer 1/1 Gbps, 2/2 Gbps, and 5/5 Gbps plans as standard. Cable operators have begun deploying mid-split and high-split upgrades to boost upload toward 100 to 300 Mbps, and DOCSIS 4.0 (see docsis-4 entry) will eventually deliver symmetrical multi-gigabit over coaxial plant. T-Mobile Home Internet typically delivers 20 to 40 Mbps upload, and Starlink delivers 10 to 25 Mbps. The Broadband Grade weights upload speed at 10% of the total score, lower than download but still meaningful enough that fiber ZIP codes systematically outperform cable ZIP codes on this subscore.

Download Speed
The rate at which data travels from the internet to your device, measured in megabits per second (Mbps). Determines how fast web pages load, videos stream, and files download.
Latency (Ping)
The time it takes for a data packet to travel from your device to a server and back, measured in milliseconds (ms). Lower latency means more responsive connections.
Mbps (Megabits Per Second)
The standard unit for measuring internet speed. One megabit equals one million bits of data. Not to be confused with megabytes (MB), which are eight times larger.
Jitter
The variation in latency over time, measured in milliseconds. High jitter causes choppy video calls, distorted VoIP audio, and rubberbanding in online games.
