A 10Gbps unmetered dedicated server is a server on a 10-gigabit port where nobody counts the bytes. Run it flat out for a month and it can move a bit over 3 petabytes in each direction. Most buyers don’t need anything close to that, and a lot of offers labeled “10Gbps unmetered” won’t deliver it anyway, so this post is about telling the two apart.
What “10Gbps unmetered” should mean
That phrase packs two promises together. “10Gbps” is the port speed, the physical ceiling on the link between your server and the host’s switch. “Unmetered” is the billing model: nobody measures your terabytes, and you pay a flat monthly price for the port.
Put them together and an honest offer means you can push up to 10 Gbps, all month, in both directions, and the invoice doesn’t change. Any limit on that belongs in the contract in plain words, not in a fair-use policy.
Here’s what the ceiling looks like as monthly volume:
| Sustained rate | Data moved in 30 days (one direction) | Compared with a 50 TB allowance |
|---|---|---|
| 154 Mbps | 50 TB | Uses all of it |
| 1 Gbps | 324 TB | 6.5× over |
| 5 Gbps | 1,620 TB | 32× over |
| 9.4 Gbps (realistic 10G ceiling) | about 3,045 TB | 61× over |
Notice the last row says 9.4, not 10. With a standard 1,500-byte MTU, Ethernet framing and TCP/IP headers eat 5 to 6% of line rate, so a clean 10G link delivers a little over 9.4 Gbps of data. Anyone promising ten full gigs is rounding up.
Who actually needs one
Most servers never get near it. If your graphs average a couple hundred megabits, buy a 1 Gbps port with a transfer allowance. It’s cheaper.
The workloads that justify 10G move big files, to lots of people or to one place, all the time:
- Video and CDN origin servers. Every cache miss at the edge pulls from origin, and a popular release sends a wave of misses at once.
- Backup and replication targets. At 1 Gbps, a 20 TB full backup takes about 44 hours to land. At 9.4 Gbps it’s under 5.
- Large file distribution. Game patches, ISOs, datasets, container images. Release day is the whole workload.
- Seedbox-scale peer-to-peer transfer. Round-the-clock upload is the exact traffic shape metered billing punishes.
- Game servers, with a caveat. Player traffic per server is small. What 10G buys a game host is room for patch downloads and some slack before a small flood fills the pipe. It is not DDoS protection, and nobody should sell it to you as that.
How it’s priced against metered and 95th percentile
There are three common ways to pay for bandwidth, and each punishes a different traffic shape.
Metered transfer gives you an allowance in terabytes and bills overage per TB. Fine for modest servers. Expensive for anything that grows.
95th percentile, or burstable billing, samples your port rate every five minutes, throws out the top 5% of samples and bills the next one. In a 30-day month that’s about 36 hours of free peaks (Wikipedia has a clear walkthrough). A four-hour evening peak every day adds up to 120 hours a month, far past the free 36, so your bill gets set by your peak instead of your average. Our own terms bill burst bandwidth above a commit this way, so I’m not knocking the model. It rewards spiky traffic, not heavy traffic.
An unmetered port charges a flat rate for the port speed. Average and peak stop mattering. You’re paying for the right to run hot.
The economics explain most of the fine print. TeleGeography’s Q2 2026 transit pricing puts the lowest 10 GigE IP transit prices at about $0.07 per Mbps per month, and the lowest 100 GigE prices at $0.03. So a fully used 10 Gbps costs a host $300 to $700 a month in transit alone at the best wholesale rates, before the server, power, space or staff.
A few hundred dollars for 10G unmetered means the host buys transit in bulk and bets that customers won’t all hit line rate at once. That’s normal. What you need to know is how much headroom they keep for the evenings when everyone does get busy. See 10G unmetered for under $100? Do the arithmetic.
The traps
Shared uplinks
A 10G port on your server says nothing about what sits behind the switch. If 40 servers with 10G ports share one 10G uplink, you won’t see 10G at 9 p.m. Ask for the access switch’s uplink capacity and its peak utilization. A host that won’t answer is answering.
“Unmetered” with a fair-use clause
This is the classic. The sales page says unmetered, and the acceptable use policy says “sustained” or “excessive” use may be throttled, capped at some number of terabytes, or dropped to a 1G port. Search the AUP and terms for “fair use”, “sustained”, “excessive” and “reasonable”. If any of them sit near the word bandwidth, get the actual threshold in writing.
A 10G port with a 1G commit
Some offers give you a 10G port with, say, 1 Gbps committed, and everything above that billed at 95th percentile. That’s a burstable plan wearing an unmetered badge. Look for the word “commit” on the order form.
Single-homed networks
Ten gigs into one transit provider is one fiber cut away from ten gigs into nothing. Ask how many upstream carriers the facility uses and whether traffic fails over between them. Then check with the host’s looking glass and a few traceroutes from where your users are.
Hardware that can’t keep up
10 Gbps is 1.25 gigabytes per second. A single SATA SSD tops out around 550 MB/s, so if you serve cold files from disk, the drives hit their wall long before the port does. Keep hot content in RAM or use NVMe. CPU matters too if every byte passes through TLS or a transcoder.
How to size it before you buy
Pull a month of port graphs from your current host. No graphs? Run vnstat or sar -n DEV for a week. Then work out three numbers:
- Your 95th percentile rate. Under about 150 Mbps, you fit in a 50 TB plan and 10G is wasted money.
- Your monthly total. Multiply your average rate in Gbps by 324 to get terabytes per month.
- Your peak and how long it lasts. If the peaks add up to more than 36 hours a month, burstable billing will charge you for them.
Then test the network, not the brochure. Run iperf3 with parallel streams (-P 8 or more) against a server near your users, because one TCP stream won’t fill 10G over any real distance. ESnet’s tuning notes say a single 10 Gbps stream across a 100 ms path needs a 120 MB buffer, far beyond Linux defaults. No test allowed before you commit? Ask for a short first term. The rest of the pre-purchase list, from CPU generation to SLA fine print, is in our dedicated server buyer’s checklist.
GigeNET’s 10G offer, as one example
Here’s ours, held to the same checklist. The Unlimited Servers page lists three packages, all on 10Gbps full-duplex unmetered ports. The entry package is $499 a month as I write this (the page shows it as 17% off a $599 MSRP), with 64 GB of RAM, two 1 TB SSDs and 4 usable IPs. The page states no data caps, no overage charges and no throttling, in both directions.
The CPUs are a pair of Xeon E5-2670 v2 chips, which Intel launched in 2013. It isn’t new silicon, and I won’t dress it up. For pushing bytes off a NIC, 20 cores and 40 threads is usually plenty; if every byte goes through heavy TLS or transcoding, test first or ask us for a newer build.
For comparison, a Chicago build on our dedicated servers page with the same CPUs, 64 GB and a 1 TB SSD runs just under $300 a month with 50 TB of bandwidth. That’s roughly $200 a month to trade a 50 TB allowance for a port you can run flat out. If your sizing math lands well above 50 TB, take the trade.
On the traps: every 10 Gbps host shares switch uplinks, us included. We watch uplink load on every rack and add capacity or stop selling into a rack before it gets tight. You can check our routing before ordering at lg.gigenet.com, which also lists a 1 GB test file for each location. Building a backup target? Two 1 TB SSDs won’t hold it, but the page says larger storage is available on request.
FAQ
No. Unmetered means the host doesn’t count your transfer, and the port speed is the limit. “Unlimited” is a marketing word that can mean almost anything, including a fair-use cap. Get the port speed and throttling policy in writing.
It shouldn’t be. An unmetered port should be flat in both directions, and our Unlimited Servers page states 10Gbps full duplex, unmetered both ways. On metered and 95th percentile plans, hosts count inbound and outbound differently, sometimes separately and sometimes summed, so ask before you point a fleet’s backups at one.
No. A bigger port raises the size of flood it takes to fill your pipe, but Cloudflare alone mitigated 935 attacks above 1 Tbps in the first half of 2026. Real protection filters traffic upstream of your port. Every GigeNET server includes baseline protection, and the tiers are on the DDoS mitigation page.
When your traffic is bursty and low on average. If your peaks total less than about 36 hours a month and your 95th percentile rate sits well under 1 Gbps, burstable billing usually wins. Steady, heavy traffic is where a flat 10G port pays for itself.
If your numbers come out above 50 TB a month, compare the packages on our Unlimited Servers page, or send your port graphs through the custom quote form and we’ll tell you whether 10G is worth it for your workload.
