25Gbps Dedicated Servers: Where the Platform Changes
You are not buying five more gigabits over the tier below. You are buying the newer chassis line that comes with them, and a port that has somewhere left to go.
X-ZoneServers 25 Gbps dedicated servers start at €1799 per month for a guaranteed 25 Gbps port — 5 bare-metal configurations with up to 8.1 PB of monthly transfer across 12 EU and US datacenter locations. The port is effectively unmetered: hold the full committed rate around the clock, with no overage charges and no fair-use throttling inside your tier.
Everywhere else in this range, a wider port makes each gigabit cheaper. At this step it does not, and the reason is worth understanding before you put the two prices side by side. Crossing from 20Gbps to 25Gbps does not simply widen the port. It changes the machine underneath it, from the Xeon E5 generation to the Dual Xeon Gold 6148, a newer and physically different chassis with a different bill of materials. The tier price follows the hardware, not the five extra gigabits. Read the number that way and the apparent regression stops being a regression. It is the boundary between a platform that has reached its last port and one that still has room ahead of it.
What a committed 25 Gbps actually moves
A guaranteed 25 Gbps port carries 3125 MB/s of payload. Over a 30-day month at full utilisation that is a sustained ceiling of 8.1 PB, and a single 1 TB dataset clears the port in 5 minutes 20 seconds. In streaming terms it is 5000 concurrent 1080p viewers at 5 Mbps, or 1000 concurrent 4K viewers at 25 Mbps. Those figures are worth stating plainly because the bandwidth on every X-ZoneServers dedicated server is guaranteed and committed per tier, with no overage charge inside it. The rate holds on the worst evening of the month, not only on a quiet Tuesday afternoon, which is the only condition under which a capacity figure is any use for planning. Up to 1Tbps of DDoS protection sits in front of the port, and the 99.9% uptime SLA applies to it in all 12 locations.
Figures use decimal units (1 Gbps = 125 MB/s) across a 30-day month, at 5 Mbps per 1080p stream and 25 Mbps per 4K stream. They describe what the port can carry, not a guarantee of application throughput: disk, CPU and the far end all apply their own limits.
5 configurations at 25Gbps
Five configurations are offered at 25Gbps. The Dual Xeon Gold 6148 opens the tier at €1799 with 40 cores and 80 threads at 2.4GHz, 256GB of DDR4-2133 and six SSD slots. The DDR5-4800 machines follow: Single EPYC 9254 at €2244, 24 cores and 48 threads at 2.9GHz with 128GB and ten NVMe slots; Dual EPYC 9254 at €2474 for 48 cores, 96 threads and 256GB on the same ten-slot layout; Dual EPYC 9554 at €2754 with 128 cores, 256 threads and 512GB across twenty-four NVMe slots; and the Dual EPYC 9754 at €3314, 256 cores and 512 threads with 1024GB. The distance between the first price and the last is not a bandwidth gap, because all five run the identical committed port. It is the compute and storage you put behind that port, which is the decision this tier is really asking you to make.

What a 25Gbps server is for
Streaming nodes you intend to keep
Serve live and on-demand video from a node you plan to re-tier rather than replace. The chassis you choose here is the one that carries the site through its next traffic step, so the hardware decision outlives the port decision by years.
Replication and backup targets
Off-site copies and database replicas that have to finish inside a window rather than merely finish. Sizing on a committed rate rather than a burst figure is the difference between a window you can schedule and one you hope for.
Regional game and patch distribution
Release-day and patch-day demand arrives as a wall rather than a curve. The dense EPYC options at this tier pair the port with enough NVMe slots to serve the same few large files to an entire region from local storage.
Multi-tenant hosting and virtualisation
Selling capacity to other people means their peaks all land at once. The DDR5 machines here bring the core counts and memory to keep tenants apart, on a platform that can take a wider port when the mix grows.
The one tier where cost per gigabit rises
Cost per gigabit is a useful number right up until it crosses a hardware boundary, and this is the crossing. At the entry configuration the ratio here is €71.96 per Gbps, against €57.95 on the 20Gbps tier. Nothing about the port is worse, and there is no surcharge attached to the tier itself. The Xeon E5 machines are offered up to 20Gbps and not above, so the cheapest server we can place behind a committed 25 Gbps port is a newer one that costs more to build. The tier below shows a better ratio because it is carried by older hardware that we buy for less. The honest version of the comparison is this: at 20Gbps you are paying for bandwidth on a platform that has finished, and here you are paying for bandwidth plus a platform that has not. Whether that is worth the difference depends almost entirely on how long you expect to keep the machine, and hardly at all on this month's traffic graph.
When 20Gbps is still the right answer
Stay below if the port is the only thing you are buying. Traffic that sits comfortably inside the 20Gbps ceiling, on a machine you expect to retire rather than re-tier, gains nothing from crossing this boundary. The E5 entry costs €640 a month less and delivers its committed rate exactly as this tier does. Take the saving, and plan a migration for the day the ceiling becomes a genuine problem.
See 20Gbps serversWhen to step up to 50Gbps
Move up when the ceiling is already the constraint rather than the plan: peaks that flatten against the port on ordinary evenings, or a fixed transfer window that will not close at this rate. The 50Gbps tier starts €1000 a month above this one and carries 16.2 PB over a 30-day month. If the chassis you chose here is also offered at that tier, the step is a port change on a machine you already run.

25Gbps dedicated server questions
Why is the price per gigabit higher here than at 20Gbps?
What does the Xeon Gold 6148 give me that the E5 line does not?
Should I skip 25Gbps and order 50Gbps instead?
How far can the machine I buy at this tier go later?
Is a 100Gbps ceiling worth paying for if I never use it?
