Meta has entered a multi-year agreement (worth up to $6B) to purchase advanced optical fiber cable and connectivity hardware from Corning.
Corning is recognized for expertise in specialty glass, ceramics, and fiber optics.
The collaboration reflects Meta’s ambitions to rapidly expand its U.S. data center infrastructure and ensure the use of state-of-the-art, domestically manufactured technology.
Corning will scale up its manufacturing capacity in North Carolina to meet the demand generated by this deal.

2. US-South Korea Tensions Over Tech Company Regulations

[01:04–01:45]

The Trump administration has warned South Korea regarding what it perceives as discriminatory actions against U.S. tech firms, amid rising trade disputes.
Vice President J.D. Vance reportedly met South Korea’s prime minister to convey these concerns.
The issue is focused on Coupang, a U.S.-based e-commerce company doing most of its business in South Korea and enjoying significant support in Washington.
Both the South Korean embassy and the vice president’s office declined to comment. The South Korean prime minister insists there is no discrimination against Coupang.

"Vice President J.D. Vance met with the South Korean prime minister last week to issue this warning... The prime minister told local media his government is not discriminating against Coupang."

3. Amazon Closing Physical Amazon Go & Fresh Stores

[01:45–02:14]

Amazon will close all 57 Amazon Fresh and 15 Amazon Go brick-and-mortar stores.
The company acknowledges these physical formats didn’t deliver a differentiated customer experience or scalable economics.
Some locations will be converted into Whole Foods stores.
Despite these closures, Amazon still intends to experiment in physical retail, with approval for its largest-ever store in Illinois.

"Amazon is closing all of its Amazon Go and Amazon Fresh physical stores... [they] failed to deliver a distinctive customer experience with an economic model that could be scaled up successfully."

Here's your afternoon TNB Tech minute for Tuesday, January 27th. I'm Julie Chang for the Wall Street Journal. Meta has struck a multi year deal worth up to $6 billion to buy fiber optic cable from Corning Cor. Corning is known for making specialty glass, ceramics and fiber optic products. It said today that it'll supply Meta with its newest generation of optical fiber cable and connectivity hardware. The company's said the move is part of Meta's plan to build major data centers across the US and to source advanced technology made domestically to meet the demand.

We exclusively report that the Trump administration is warning South Korea against discriminatory regulations and investigations targeting US Tech companies amid rising trade tensions. People familiar with the matter say. Vice President J.D. vance met with the South Korean prime minister last week to issue this warning. Many recent discussions involve Coupang, a U S based e commerce company similar to Amazon. It does nearly all its business in South Korea and and has allies in the Trump administration and Congress. The vice president's office declined to comment. The South Korean Embassy in Washington didn't respond to requests for comment on the meeting, but the prime minister told local media his government is not discriminating against couping and Amazon is closing all of its Amazon Go and Amazon Fresh physical stores. The company said today that its branded stores failed to deliver a distinctive customer experience with an economic model that could be scaled up successfully. According to an Amazon spokeswoman.

How are data center operators working to improve sustainability and water savings at every stage of the data center lifecycle? Here's Ecolabs Christoph Beck with some thoughts.

Christophe Beck
The Mach 7 or the Mach 4 are the ones who are really so focused on high tech are the most forward looking. They have the means, they have the mindset, they have the passion for innovation and they're really open to try new things as well, because everything is new with AI and with that technology as well. I think even if we're not where we wanted to be with that industry right now, we will be ahead in the next few years because innovation that's coming up right now is working much better than we thought. And it's really thinking in circular ways, being in a data center or in a microchip manufacturing plant.
