WebARENA Indigo is a VPS service from NTTPC Communications, the docomo business network operator. It targets first-time VPS users, learners, and cost-conscious developers who want a simple server without signing up for a long-term plan.

Billing is hourly and applies whether the instance is running or stopped. Each plan has a monthly cap that prevents unexpected charges. Rates stay flat, with no campaign pricing or contract-length discounts to compare. Data transfer is free, and new users get a starter coupon to try the service at low risk. Plans range from a small 1 vCPU tier up to larger instances, all running on NTT Group network infrastructure.

Users can save disk snapshots from the web control panel for point-in-time recovery before risky changes, such as kernel upgrades or configuration edits.

A separate Windows VPS lineup runs alongside the Linux plans for .NET workloads, Remote Desktop, and other Windows-only software.

The control panel and customer support are primarily in Japanese. Some product information is also published in English through the wider NTTPC Group for international teams working in Japan.
