InterServer VPS Plans – The Slice System
Instead of fixed Small/Medium/Large plans, you buy “slices” of a server and stack as many as you need. Pricing is linear, so doubling resources roughly doubles the bill.
| Slices | Approx. Resources | Scaling | From (approx.) |
|---|---|---|---|
| 1 slice | 1 vCPU / 2 GB RAM | Entry | ~$6/mo |
| 2 slices POPULAR | 2 vCPU / 4 GB RAM | Small sites | ~$12/mo |
| 4 slices | 4 vCPU / 8 GB RAM | Apps & stores | ~$24/mo |
| 8 slices | 8 vCPU / 16 GB RAM | Heavy workloads | ~$48/mo |
Figures are indicative and based on the per-slice model. Promotions and plan details change, so confirm on the InterServer website before ordering.

Is InterServer Worth It?
InterServer isn’t the cheapest option on the first invoice, and it isn’t trying to be. Its appeal is that the price you sign up at is the price you keep, from a provider that owns its own infrastructure. If you value a steady bill and a clear upgrade path from shared hosting to VPS to dedicated, it’s an easy recommendation. If you need servers in many regions or the lowest possible intro price, compare alternatives first.
InterServer – Frequently Asked Questions
What is the InterServer price lock?
It’s a guarantee that your monthly rate stays the same for as long as you keep the service, rather than jumping at renewal. Check the current terms on InterServer’s site.
What is a “slice”?
A slice is a fixed bundle of CPU, RAM, storage and bandwidth. You choose how many slices to combine, so you scale by adding more rather than picking a preset plan.
Is InterServer managed or unmanaged?
VPS plans are self-managed with full root access by default. Managed VPS plans are available at a higher price if you want help with administration.
Where are InterServer’s servers located?
Its main infrastructure is in a facility it owns in Secaucus, New Jersey, so it’s best suited to US-focused audiences.
Does InterServer offer Windows VPS?
Yes, Windows VPS is available alongside Linux, and so are WordPress, Webuzo and storage-focused VPS options.
Can I upload my own operating system?
Yes, custom ISO uploads are supported, which is useful for specialised or hardened images.
Can I upgrade later?
Yes. VPS resources scale by adding slices, and you can move up to dedicated servers or colocation within the same provider.
