InterServer runs its Cloud VPS platform from its own US data centers — primarily Secaucus, New Jersey, with Los Angeles, California available for West-Coast and Asia-Pacific routing. Because InterServer owns the hardware and the network, you are not sharing an oversold public-cloud region.
LATENCY TIP
From the NJ data center you get 20-45 ms across North America and roughly 85-110 ms to Western Europe. For visitors in India or Asia-Pacific, deploy in LA and put Cloudflare (free) in front — that pulls real-world load times into the sub-130 ms range.
InterServer VPS is genuinely flexible on the software stack — you are not locked into one image. At deployment you choose your OS, and you can reinstall it later from the control panel.
| Layer | Options | Notes |
|---|---|---|
| Linux | Ubuntu, Debian, AlmaLinux, Rocky Linux, CentOS, Fedora | Free — the default choice for web hosting and apps |
| Windows | Windows Server (licensed) | For .NET, MSSQL, or Windows-only software — small monthly licence fee |
| Control panel | DirectAdmin (free), cPanel (+$25/mo), Plesk | DirectAdmin covers WordPress, email and DNS at no cost |
If you are comfortable on the command line, run it unmanaged with no panel and keep every dollar of resource for your app. If you want a GUI, DirectAdmin is the value pick — cPanel only makes sense if your team already lives in cPanel.
The slice model is the main reason to choose InterServer VPS: you start small and add capacity in even steps as traffic grows, with no platform migration. Here is when to scale:
You can scale up to 16 slices on a single VPS. Adding slices is a control-panel change, not a rebuild — your data, IP and configuration stay exactly as they are. That makes InterServer VPS a safe place to start a project you expect to grow.
<<DirectAdmin is included free and handles WordPress, email, DNS and databases. cPanel is available for an extra $25/month and Plesk is also offered. You can also run the VPS with no panel at all if you prefer the command line.
Yes. InterServer VPS supports Windows Server alongside its Linux images, so you can host .NET applications, MSSQL, or other Windows-only software. A small monthly Windows licence fee applies on top of the slice price.
One to two slices is plenty for a single WordPress site or a small app. Add slices when CPU sits above 80% under normal load or RAM-heavy workloads start swapping. You can scale up to 16 slices, so it is safe to start small.
Yes — DDoS protection is filtered at the network edge and included free on every VPS plan, along with a 1 Gbps network and a dedicated IP. You still handle software-level hardening (firewall rules, updates) yourself on an unmanaged plan.
Adding slices is a control-panel operation that keeps your data, IP and configuration intact — there is no platform migration. A brief reboot may apply when new resources are attached, but you are not rebuilding the server.
