Thousands of Vodafone customers across the UK have reported its services are down.

Downdetector, which monitors web outages, showed more than 130,000 people had flagged problems affecting their Vodafone broadband or mobile network on Monday afternoon.

According to its website, the firm has more than 18 million customers in the UK, including nearly 700,000 home broadband customers.

Vodafone said in a statement it was aware of a “major issue on our network affecting broadband, 4G and 5G services”.

“We appreciate our customers’ patience while we work to resolve this as soon as possible,” the company said.

It comes as people on social media say they are struggling to access Vodafone customer service operators amid ongoing issues affecting mobile data and broadband.

Many have also said they are having difficulty accessing the company’s website and app, which typically allow people to view the status of its network services.

Customers have also taken to social media to complain of “complete outages” in their area.

The issues appear to have begun for customers shortly after 15:00 BST.

Internet monitor Netblocks said in a post on X, live network data showed Vodafone was experiencing “a national outage” impacting both broadband and mobile data.

Some customers have expressed being doubly frustrated by not being able to access their Wi-Fi or mobile data.

“Sort it out soon please,” wrote one frustrated X user – who said they were having to use a coffee shop’s Wi-Fi to access online services without the means to do so using their mobile data or broadband.

Another said they were self-employed and could not work because of the outage, adding: “Never regretted more having my mobile and broadband on the same network.”

The issues affecting Vodafone services are also impacting customers of other telecoms firms that use its network.

Downdetector saw a similar spike in reports on Monday afternoon from users of the mobile network Voxi, which is owned by Vodafone.

Lebara, which piggy-backs off Vodafone’s network, has also been affected by the company’s outage.

News Summary:

• Meta to introduce switches built on NVIDIA Spectrum Ethernet for its Facebook Open Switching System platform.     
• Oracle to build giga-scale AI supercomputers with Spectrum-X Ethernet switches.

OCP—NVIDIA today announced that Meta and Oracle will boost their AI data center networks with NVIDIA Spectrum-X™ Ethernet networking switches.

Meta and Oracle are standardizing on Spectrum-X Ethernet switches as an open, accelerated networking architecture that speeds deployment at scale, unlocks exponential gains in AI training efficiency and shortens time to insights.

“Trillion-parameter models are transforming data centers into giga-scale AI factories, and industry leaders like Meta and Oracle are standardizing on Spectrum-X Ethernet to drive this industrial revolution,” said Jensen Huang, founder and CEO of NVIDIA. “Spectrum-X is not just faster Ethernet — it’s the nervous system of the AI factory, enabling hyperscalers to connect millions of GPUs into a single giant computer to train the largest models ever built.”     

Oracle will build giga-scale AI factories accelerated by the NVIDIA Vera Rubin architecture and interconnected by Spectrum-X Ethernet.

“Oracle Cloud Infrastructure is designed from the ground up for AI workloads, and our partnership with NVIDIA extends that AI leadership,” said Mahesh Thiagarajan, executive vice president of Oracle Cloud Infrastructure. “By adopting Spectrum-X Ethernet, we can interconnect millions of GPUs with breakthrough efficiency so our customers can more quickly train, deploy and benefit from the next wave of generative and reasoning AI.”

Meta will integrate Spectrum Ethernet switches into its networking infrastructure for the Facebook Open Switching System (“FBOSS”), a software platform developed to manage and control network switches at massive scale. This integration will speed deployment at scale to unlock gains in AI training efficiency and shorten time to insights.

“Meta’s next-generation AI infrastructure requires open and efficient networking at a scale the industry has never seen before,” said Gaya Nagarajan, vice president of networking engineering at Meta. “By integrating NVIDIA Spectrum Ethernet into the Minipack3N switch and FBOSS, we can extend our open networking approach while unlocking the efficiency and predictability needed to train ever-larger models and bring generative AI applications to billions of people.”

NVIDIA Spectrum-X Ethernet Platform

Designed for the trillion-parameter model era, the NVIDIA Spectrum-X Ethernet platform, consisting of Spectrum-X Ethernet switches and Spectrum-X Ethernet SuperNICs, is the first Ethernet platform purpose-built for AI, enabling hyperscalers to interconnect millions of GPUs with unprecedented efficiency and scale.

Trillion-parameter models and generative AI are redefining the scale of data centers. Spectrum-X Ethernet enables AI at scale, delivering the performance and scalability needed to build the world’s most advanced AI infrastructure.

Spectrum-X Ethernet has already demonstrated record-setting efficiency, enabling the world’s largest AI supercomputer to achieve 95% data throughput with its congestion-control technology. By contrast, off-the-shelf Ethernet at scale suffers from thousands of flow collisions, limiting throughput to roughly 60%.

This leap in efficiency marks a breakthrough in the economics and performance of AI-scale networking. NVIDIA Spectrum-XGS Ethernet technology, part of the Spectrum-X Ethernet networking platform, enables scale-across capabilities to link data centers across cities, nations and continents into vast, giga-scale AI super-factories.

Spectrum-X builds on NVIDIA’s full-stack platform — including GPUs, CPUs, NVIDIA NVLink™ and software — to deliver seamless performance from compute to network. Its advanced congestion control, adaptive routing and AI-driven telemetry capabilities ensure efficiency and predictability for massive AI training and inference clusters.
