Verizon Fiber reaches half of Boston homes with speeds cable can't match

Boston has nearly ubiquitous wireline broadband coverage, with 97.8 percent of addresses able to get cable broadband above 100/20 Mbps from Comcast, according to industry data. Verizon Fiber, meanwhile, reaches about half of the city's units [1]. Yet the gap between the two providers, in raw speed, if not reach, is stark.

Verizon Fios is the fastest internet provider in Boston, with median download speeds of 302.43 Mbps, and offers symmetric speeds up to 2,048 Mbps in parts of the city [2]. Xfinity, the most popular provider, delivers typical speeds of 139 Mbps download and 23 Mbps upload, with a maximum of 2 Gbps [3]. The difference isn't academic: For anyone working remotely, running a home business, or streaming in 4K, those numbers translate into real-world lag and load times.

The equity gap beneath the speed stats

Speed isn't the only story. Despite 25 Mbps service being available in every block of the city, symmetrical 100 Mbps/100 Mbps broadband speeds are not available in 27.2 percent of Boston's populated blocks [4]. That means nearly three in ten blocks lack the kind of upload capacity now essential for video calls, cloud backups, and telehealth appointments. For a city that bills itself as a global deep-tech hub, Boston ranks third nationally for AI-focused venture capital with $11.6 billion invested since 2019, and the average software engineer base salary is $167,559 as of April 2026 [3], the connectivity disparities are hard to ignore.

Residents have 4 to 8 ISPs to choose from, depending on location, including Verizon, Xfinity, Astound Broadband, Starry, and EarthLink Fiber [5]. Fiber remains the fastest connection type, but its overall availability still lags behind cable [5]. That leaves many Bostonians stuck choosing between the most widespread provider (Xfinity) and the fastest one (Verizon), even as the city aims to reach net-zero greenhouse gas emissions by 2050 and pursues upgrades like the $11 million first phase of its $45 million Renew Boston Trust initiative [1][4].

What to do if you're shopping for speed this month

For anyone in a Verizon Fiber-served building, the choice is straightforward: Fios's median 302.43 Mbps download and symmetric upload speeds make it the clear winner for heavy internet users [2]. For those outside Verizon's fiber footprint, Xfinity's cable offering, with typical speeds of 139 Mbps down and 23 Mbps up, remains the default [3]. But even Xfinity's 2 Gbps maximum can't match Verizon's 2,048 Mbps symmetric tier in the areas where both compete [2][3].

The practical takeaway is a familiar one in Boston's unequal broadband market: Check your address carefully. Fiber availability can vary street by street, and the city's own digital equity assessment identifies persistent gaps [3]. With Massachusetts startups raising $16.7 billion in venture capital in 2025, a 12% increase over 2024, and Boston solidifying its position as the world's premier deep-tech sanctuary in 2026, the demand for high-speed, low-latency connectivity is only going to grow [2][3].
