Google Fiber already offers 20 Gig internet speeds, but it's preparing to push that to 50Gbps.

The company partnered with Nokia to successfully test the 50Gbps technology on a live network at a Google Fiber hub in Kansas City. 

In a video, Google Fiber—now known as GFiber—delivers an impressive 41.89Gbps download speed and a 19.6Gbps upload rate. (Data from Ookla's Speedtest.net displayed in the video put the download rate closer to 8.1Gbps for some reason.)

Google is upgrading its existing fiber network by tapping Nokia’s next-generation passive optical network (PON) technology. This allows the fiber network to simultaneously run 10 Gig and 20 Gig internet speeds alongside the faster 50 Gig test service. 

The 50 Gig broadband will probably be overkill for most users. Still, Google says the speed advancements are necessary to future-proof its network for next-generation video streaming, virtual reality, and AI applications, which will likely require far more data. 

“Multigig is already the new norm,” Google says in a blog post. “But to meet the challenge of this connected future, we are preparing to further densify our network so when bandwidth needs inevitably multiply, we’ll be ready.” 

Although it’ll probably take GFiber a few years to commercialize the 50 Gig speeds, the company is already preparing to expand the existing 20 Gig offering to more areas. “It’s why we’re now working to deploy Nokia 25G PON in all of our markets by the end of the year, so that we can extend access to GFiber Lab’s 20 Gig plan,” the company said. 

GFiber's 20 Gig speed plan, which costs $250 per month, has only rolled out to select users in Kansas City, North Carolina's Triangle Region, Arizona, and Iowa.

After 50Gig is reached, GFiber plans to push the speeds even further to 100Gbps. Rival ISP Ziply also offers 50Gbps internet in the Pacific Northwest, but it costs $900 per month.

GFiber topped our Readers' Choice rankings of the Best ISPs for 2024, receiving the highest ratings in our survey for overall satisfaction and likelihood to recommend, as well as satisfaction with connection reliability, speed, and value. It finishes behind only Starlink for satisfaction with ease of use. It also scored well on our roundup of The Best Internet Service Providers for 2024.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
