A guaranteed 25 Gbps port. Not “up to”.
Most “unmetered” hosting sells a shared “up to 25 Gbps” buried in fine print. Here the 25 Gbps port is for your server alone, with guaranteed capacity and no traffic quota. And we publish our iperf3 measurements: indicative and untouched.
Three very different things with the same name.
“Unmetered”, “up to X Gbps” and “guaranteed port” sound alike and cost wildly differently. The difference: whether you share the port with others, and whether traffic is billed.
Guaranteed port (dedicated)
The 25 Gbps port is for your server alone and is not shared with other customers. Guaranteed capacity, no traffic quota, and we don't throttle speed based on volume. It is what serious production needs.
Shared / “up to”
A 25 Gbps port split across many servers. The “up to” is the port’s ceiling, not your share: you compete with your neighbours for the same capacity.
Metered (with quota)
Traffic counted per TB: speed can be good, but every terabyte adds to the bill, and going over means throttling or overage fees. With large, sustained loads, the bill is unpredictable.
We tested the network and published the numbers.
Before offering these servers we ran iperf3 load tests from a 40 Gbps dedicated box in central Europe. These are the results, unedited and indicative only.
Our own iperf3 measurements (July 2026) from a 40 Gbps dedicated server in Frankfurt against the London datacenter. Indicative results: effective speed depends on the remote end and the route.
When moving data is your job.
If your workload lives on pushing or pulling a lot of data continuously, a dedicated, quota-free 25 Gbps port stops being a luxury: you don’t share it with other customers or pay for every TB.
CDN and file distribution
Serve downloads, updates and heavy content to many users at once, without paying for every TB served: we don’t cap speed based on volume.
Backups and mass storage
Upload and restore terabytes without watching the bill: with no traffic quota, a 5 TB backup triggers no overage charges.
AI: datasets and inference
Move huge datasets between nodes and serve models under many concurrent requests, on a dedicated 25 Gbps port with no traffic quota.
Dense virtualization
Dozens of VMs or containers behind a 25 Gbps port that belongs to your server alone. You decide how it’s split between instances — not your neighbors.
Mirrors and repositories
Repo mirrors, container registries or package replicas that many clients hit at once, with a guaranteed 25 Gbps port for your server alone.
Voice, gaming and real-time
Voice servers, game servers and real-time backends in London, on a dedicated port you don’t share with other customers.
Out there, 25 Gbps costs something else.
A dedicated, quota-free 25 Gbps port is not cheap on the market — when you even find it published. Most “budget” hosting at that number sells you something else.
| Provider | What you get | Price/mo approx. |
|---|---|---|
| 25G specialists | 25 Gbps committed bandwidth | ~€1,800 |
| One-off deals | Occasional 25 Gbps unmetered | ~€550-650 |
| Typical “budget” dedicated | 1-3 Gbps guaranteed (the 25G is private) | ~€90-280 |
| PulsarHost | Guaranteed 25 Gbps port, unshared, no quota | from €255.99 |
References: public prices of European and North American providers, August 2026 (entry plan, ex-VAT, rounded). The “budget dedicated” usually advertises 1-3 Gbps guaranteed public bandwidth and reserves the 25 Gbps for the private network. Always check the provider’s page.
