Culvert VPN's Bangladesh location is Dhaka, and it is a Premium city. It gives you a Bangladeshi exit address and is the only Culvert server inside the country, so for anyone in Bangladesh it is far closer than the next options in Mumbai and Singapore. The free tier does not include it.

Where the server is

Dhaka is where Bangladesh's domestic network converges: the fibre from Chittagong, Sylhet, Khulna and the rest of the country meets in the capital, and the international routes leave from there towards the cable landings on the coast. That is why a server in Dhaka keeps a Bangladeshi user's traffic inside the country's own network and gives a round trip that no server abroad can match.

The picker shows Bangladesh as a country row with Dhaka beneath it. Tapping either connects to the same city.

Latency from nearby regions

Estimated from distance at roughly a millisecond per 100 km each way plus routing overhead. Bangladesh is compact, so domestic figures are low; the international ones are higher than the map suggests because the cables run around the Bay of Bengal rather than across it. These are what the app should measure from a phone on a good connection:

FromTypical round trip
Dhaka and Gazipur2–10 ms
Chittagong5–15 ms
Sylhet, Rajshahi, Khulna5–18 ms
Kolkata6–20 ms
Guwahati10–25 ms
Kathmandu15–32 ms
Yangon20–45 ms
Delhi28–50 ms
Mumbai38–65 ms
Bangkok30–55 ms
Singapore50–80 ms

Two things push real numbers higher. Mobile data adds the carrier's own delay, often 20–40 ms on 4G and more at peak hours, and most people in Bangladesh are on mobile data, so the figure in the picker will usually sit at or above the top of the range. And routes to neighbours do not always follow the map: traffic to Kolkata, only 250 km away, can travel out to Singapore and back if the direct overland route is not the one your provider uses. The VPN on mobile data post covers what to expect from a phone on 4G.

Who this location suits

People in Bangladesh who want a server that is actually nearby. From anywhere in the country, Dhaka is within about 20 ms on a fixed line and is the only Culvert city that does not send your traffic out through the submarine cables and back. Expats living in Bangladesh who want a local exit address use it too.

Anyone on shared Wi-Fi. University halls, hostels, offices, hotels, coworking spaces and cafés share one router among strangers, and whoever runs the network can see the destinations of everyone's traffic. A VPN to Dhaka turns yours into one encrypted stream to a single Bangladeshi address. Where a network filters ports or blocks common VPN protocols, the app tries several connection methods in order and keeps the one that works; the campus Wi-Fi post describes what that looks like.

Checking a service from Bangladesh. A Bangladeshi exit address lets a developer see what a visitor there is served: Bengali language detection, taka pricing, which CDN edge answers, and how long their own site takes to load from inside the country on a mobile connection, which is what most of their users will experience. It is also the place to reproduce a report from a customer in Bangladesh.

How the app measures it

The Dhaka row shows a round trip measured from your phone to the city at the moment the picker opens, in milliseconds, and a headroom figure for how much capacity the city has spare. Both are real measurements, updated each time you look. The table above is an estimate from geography; the number in the app comes from your own network and is the one to trust. The headroom figure separates a busy server from a long route, which a speed test alone cannot.

Tapping Bangladesh connects you to its lowest-latency healthy city, and inside the city the app picks the healthiest server itself. Individual servers are never listed, so a server drained for maintenance or given a new address changes nothing you can see. Once connected, the exit IP on screen is one the app verified through the tunnel by asking Culvert's own server what address it saw.

Dhaka is one of Culvert VPN's Premium locations, billed through Google Play and usable on up to five devices; the app is on Google Play.

Questions people also ask

Is the Dhaka server free?

No. Free servers are in the Netherlands, France and Germany. Dhaka is a Premium location, billed through Google Play in taka.

What is the nearest alternative to Dhaka?

Mumbai, then Singapore. Both are usually 40–80 ms from Bangladesh, whereas Dhaka is under 20 ms from most of the country on a fixed connection. The picker shows a measured figure for each.

Why is the round trip to Singapore so much higher than the map suggests?

Much of Bangladesh's international traffic leaves through submarine cables that land at Cox's Bazar and Kuakata and run around the Bay of Bengal, so the cable path is a lot longer than the straight-line distance.
