Infrastructure company Azio AI Holdings signed a master services agreement (MSA) with AT&T worth roughly $2.4 million to provide enterprise fibre connectivity for its first AI data centre campus.

The deal covers a 500-megawatt site and establishes a standardised connectivity framework across the campus, delivering the high-capacity, low-latency network infrastructure needed to support AI training, inference, GPU cloud computing, enterprise colocation, and other high-performance computing workloads.

Azio said the connectivity buildout is intended to streamline network deployment as it brings on additional customers under its hyperscale AI strategy. The company pointed to a recent power purchase and hosting agreement with a GPU customer, which it said will require a rapid, modular buildout at the Texas site.

“This agreement establishes the networking framework supporting our initial 500-megawatt Texas AI platform while creating a scalable operating model that can support future expansion as additional projects move forward under our hyperscale AI strategy,” Azio COO Elgin Tracy stated.

The company’s broader strategy centres on scalable, liquefied natural gas-backed energy capacity intended to meet rising demand for GPU cloud and AI workloads.

It stated the Texas site was picked in part due to the location being able accommodate large-scale industrial infrastructure without the land-use and community constraints which can complicate data centre projects in urban areas.

The agreement adds AT&T to the growing list of telecoms operators positioning themselves as connectivity partners for the AI infrastructure buildout, as data centre operators race to secure the fibre capacity needed to link GPU clusters to enterprise and hyperscale customers.

Azio did not disclose a timeline for construction completion or when the Texas campus is expected to become operational.

AT&T switched on a dedicated standalone (SA) 5G core for public safety network FirstNet, which the operator described as the first and only such nationwide network built specifically for first responders.

The new core is physically separate from AT&T’s commercial network infrastructure, a design intended to give public safety agencies greater security, reliability and control over their connectivity.

AT&T stated the architecture was shaped by feedback from first responders and is intended to meet operational needs which differ meaningfully from everyday consumer use.

Scott Agnew, president of FirstNet at AT&T, said the SA core was purpose-built around the mission of public safety rather than adapted from a consumer network.

“This milestone keeps America’s public safety network strong for the future, because when our first responders succeed, our communities are safer.”

AT&T stated the dedicated core functions as the central nervous system for the FirstNet network, keeping public safety traffic separate from commercial traffic.

It runs across multiple geographically-distributed core sites to add redundancy, an approach AT&T stated improves performance and resilience.

The upgrade also brings faster upload data rates and improved responsiveness, capabilities AT&T stated are increasingly necessary as first responders adopt connected tools including body-worn cameras and mission-critical communications applications.

Security beyond the standard measures used on commercial networks is built into the core.

Access is restricted to devices using a FirstNet SIM, which it stated protects subscriber data from potential attackers, while a dedicated security operations centre monitors the network around the clock for threats.

Adaptive Mission Performance
AT&T positioned the service as groundwork for a broader initiative called Adaptive Mission Performance to tailor network performance to specific public safety applications and use cases rather than relying on a single network slice from commercial infrastructure.

The operator stated it plans to deploy the capabilities over time as more subscribers migrate to the new core.

FirstNet subscribers are already being transitioned to the new core at no additional cost.

While laying claim to a nationwide launch, AT&T did note the service requires a compatible device and plan, and it is not available everywhere.

The operator deployed its SA 5G core in 2025, five years later than T-Mobile US.

Verizon Frontline rolled out its service in select markets in 2025.

T-Mobile and Verizon are using their SA 5G cores to provide network slicing for first responders.
