International web bandwidth elevated by 23% in 2025, sustaining its constant tempo of regular development.
Whole worldwide bandwidth now stands at a powerful 1,835 Tbps, representing a four-year compound annual development charge (CAGR) of 24%.
Though the tempo of development has slowed ever so barely in recent times, bandwidth has nonetheless greater than doubled since 2021.
Naturally, capability development varies throughout completely different areas. As soon as once more, Africa led the best way with essentially the most fast development in worldwide web bandwidth, increasing at a compound annual charge of 38% between 2021 and 2025. The Center East adopted, rising at a 27% compound annual charge over the identical interval.
Worldwide Web Bandwidth Development by Area
The mixed results of recent internet-enabled units, rising broadband penetration in creating markets, larger broadband entry charges, and bandwidth-intensive functions will proceed to gasoline robust web site visitors development.
Whereas end-user site visitors necessities will proceed to rise, not all of this demand will translate instantly into the necessity for brand new long-haul capability.
A wide range of components form how the worldwide web will develop within the coming years:
Synthetic Intelligence (AI)
That is essentially the most hyped demand driver in recent times, however its affect on worldwide web capability will not be completely clear. The impact of AI is not going to be solely felt within the networks of the massive cloud suppliers concerned in AI, comparable to Amazon, Google, Meta, and Microsoft.
Many firms are providing GPUs-as-a-Service (GPUaaS), which permits anybody entry to GPUs to coach their very own fashions or use them for inference. As customers deploy AI fashions and inference clusters utilizing these GPUs, the site visitors will finally run via the networks of many operators, not simply these of the foremost cloud suppliers.
Bypassing the Public Web
The most important content material suppliers have lengthy operated huge networks.
These firms proceed to expertise extra fast development than web backbones, and they’re increasing into new areas. Many different firms, comparable to cloud service suppliers, CDNs, and even some knowledge middle operators, function personal backbones that bypass the general public web. Consequently, a rising share of worldwide site visitors is carried by these networks.
Worldwide Necessities of New Functions
Whereas there’s little doubt that enhanced end-user entry bandwidth and new functions will create massive site visitors flows, it isn’t clear how a lot of this development would require the usage of worldwide hyperlinks.
Within the close to time period, the elevated reliance on direct connections to content material suppliers and the usage of caching will proceed to have a localizing impact on site visitors patterns, dampening worldwide web site visitors development.
IP Transit Worth Erosion
Worldwide transport unit prices underlay IP transit pricing. As new worldwide networks are deployed, operational and building prices are distributed over extra fiber pairs and extra energetic capability, making every packet inexpensive to hold.
We’re already seeing a significant shift from 10 GigE necessities to 100 GigE necessities, and we anticipate that 400 GigE will emerge in two to 3 years as a big a part of the market.
The introduction of recent worldwide infrastructure additionally creates alternatives for extra regional localization of content material and fewer dependence on distant hubs. As rising markets develop in scale, they will even profit from economies of scale, even when solely via cheaper transport to web hubs.
