International web bandwidth elevated by 23% in 2025, sustaining its constant tempo of regular development.
Complete worldwide bandwidth now stands at a formidable 1,835 Tbps, representing a four-year compound annual development price (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 speedy development in worldwide web bandwidth, increasing at a compound annual price of 38% between 2021 and 2025. The Center East adopted, rising at a 27% compound annual price over the identical interval.
Worldwide Web Bandwidth Progress by Area
The mixed results of latest internet-enabled units, rising broadband penetration in creating markets, larger broadband entry charges, and bandwidth-intensive purposes will proceed to gasoline sturdy web visitors development.
Whereas end-user visitors necessities will proceed to rise, not all of this demand will translate immediately into the necessity for brand spanking 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 influence on worldwide web capability is just not solely clear. The impact of AI is not going to be solely felt within the networks of the big cloud suppliers concerned in AI, resembling Amazon, Google, Meta, and Microsoft.
Many corporations 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 visitors will finally run by means of 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 corporations proceed to expertise extra speedy development than web backbones, and they’re increasing into new areas. Many different corporations, resembling cloud service suppliers, CDNs, and even some information middle operators, function non-public backbones that bypass the general public web. Because of this, a rising share of worldwide visitors is carried by these networks.
Worldwide Necessities of New Functions
Whereas there’s little doubt that enhanced end-user entry bandwidth and new purposes will create massive visitors flows, it is not 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 visitors patterns, dampening worldwide web visitors development.
IP Transit Value Erosion
Worldwide transport unit prices underlay IP transit pricing. As new worldwide networks are deployed, operational and development prices are distributed over extra fiber pairs and extra energetic capability, making every packet inexpensive to hold.
We’re already seeing a serious shift from 10 GigE necessities to 100 GigE necessities, and we anticipate that 400 GigE will emerge in two to a few years as a big a part of the market.
The introduction of latest 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 may also profit from economies of scale, even when solely by means of cheaper transport to web hubs.
