BDIX VPS in Bangladesh: what to check before you buy one

Search for a VPS in Bangladesh and nearly every result says BDIX. The plans look alike: a few cores, some RAM, "NVMe", "up to 10 Gbps". What decides how the server behaves is in the small print, and most buyers only find it after the first month.

This guide covers what a BDIX VPS is, the four spec-sheet lines worth reading closely, how to test a provider before you pay, and how to pick a starting size.

What a BDIX VPS is

A VPS (virtual private server) is a slice of a physical server with its own operating system, CPU cores, RAM and disk, and you control it with root access. "BDIX" means the server is in Bangladesh and connected to the Bangladesh Internet Exchange, where local ISPs hand traffic to each other directly.

So a visitor on a Bangladeshi broadband connection reaches the server without their traffic leaving the country. Round trips drop from the 60 to 120 ms you typically see to Singapore to around 10 ms or less, and downloads run at local exchange speeds instead of squeezing through international capacity. We explain the routing in more detail in BDIX hosting, explained.

The four spec-sheet lines that matter

1. BDIX speed and IIG bandwidth are two different numbers

Every BDIX VPS has two ways out. The BDIX side carries traffic to and from Bangladeshi networks. The IIG side (International Internet Gateway) carries everything else: Google, Cloudflare, GitHub, package mirrors, Telegram, and every visitor from abroad.

Providers headline the BDIX number because it is big. The IIG number is usually far smaller and almost always shared between customers. If your server pulls Docker images, calls an API hosted abroad, or serves anyone outside Bangladesh, the IIG figure is the one you will feel.

A plan worth trusting states both, for example "BDIX 1 to 10 Gbps, IIG up to 100 Mbps (shared)". A plan that only mentions BDIX is leaving out the number you need.

2. KVM, not containers

KVM gives you a real virtual machine with its own kernel. You can run Docker, WireGuard, custom kernel modules and any Linux distribution, and another customer cannot borrow your RAM. Container-based VPS (OpenVZ, LXC, Virtuozzo) shares the host's kernel. It is cheaper to run, but some software will not install and resource guarantees are softer.

If the plan does not name its virtualisation, ask. If the answer is not KVM, price it as a lesser product.

3. NVMe, and how much of it

NVMe drives handle many times more read and write operations per second than SATA SSDs, which is what databases and busy WordPress sites care about. "SSD" on its own usually means SATA. Check the disk size against what you will actually keep there: logs, backups and Docker images fill a 20 GB disk faster than people expect.

4. A dedicated IPv4 and the monthly quota

You want your own IPv4 address, not a NAT range of a few ports, so you can run websites, game servers and anything else that needs inbound connections on standard ports. Then check the monthly bandwidth quota. A 10 Gbps BDIX port next to a 500 GB monthly limit is fast, but only until the limit runs out.

How to test a provider in five minutes

Ask for a test IP or looking-glass address. Most providers have one. Then run these from the connection your visitors actually use:

# Round trip. Under ~15 ms from Bangladeshi broadband means a local route
ping -c 20 203.0.113.10

# Path. A BDIX route stays on Bangladeshi networks from start to finish
traceroute 203.0.113.10      # on Windows: tracert 203.0.113.10

# Throughput, if they publish a test file
curl -o /dev/null -w "%{speed_download} bytes/s\n" http://203.0.113.10/100MB.bin

Test from broadband and from mobile data. They do not always take the same path, and most people in Bangladesh browse on their phones.

Once you have a server, test the other direction too: update packages or download a large file from abroad in the evening. That shows you what the shared IIG capacity is like at busy hours, which no spec sheet will tell you.

Which size to start with

Start small. On KVM, moving to a bigger plan is usually a short restart, and paying every month for RAM that sits idle is one of the most common VPS mistakes.

When a BDIX VPS is the wrong choice

If most of your users are outside Bangladesh, put the server near them. A BDIX VPS serves foreign visitors over shared IIG bandwidth, so they get a slower site than they would from a server in Singapore or Europe. Our list of what gains from BDIX and what does not goes through common workloads one by one.

And if all you need is a WordPress site, BDIX shared hosting is cheaper and someone else handles the updates and security. A VPS earns its price when you need root access, custom software or resources nobody else can borrow. Our guide to outgrowing shared hosting covers the signs.
