When you connect to ftp.zentransfer.io, you are automatically routed to the server closest to your current location. Behind that single hostname is a network of edge nodes distributed across the globe.

This article covers where those nodes are, why they exist, and how they help you get your files where they need to go faster.

Why Edge Nodes Matter

FTP performance is heavily influenced by network latency. Every command and data transfer between your camera or client and the server is affected by the physical distance the packets must travel. A photographer covering an event in Tokyo uploading to a server in Virginia will experience noticeably slower transfers than one uploading to a nearby node in Japan.

By placing servers in key regions around the world, we reduce the round-trip time for every connection. This translates directly into faster uploads, more reliable transfers over unstable connections (such as mobile hotspots at events), and better throughput for large files.

Edge nodes also provide resilience. If one region experiences issues, traffic is rerouted to the next closest healthy node. There is no single point of failure.

Our Current Edge Nodes

We currently operate nine regional FTP servers:

Each node runs the same ZenTransfer FTP server software, supports FTP over TLS (FTPS), and connects to the same backend infrastructure for file delivery. Your experience is identical regardless of which node handles your connection.

The power of ZenTransfer lies in our very own FTP server software which is purpose-built for photography workflows.

How Routing Works

When you point your camera or FTP client at ftp.zentransfer.io, DNS-based traffic management resolves the hostname to the IP address of the nearest healthy edge node. This happens transparently -- you do not need to configure anything or choose a region manually.

If you prefer to connect to a specific region, you can use the regional hostname directly (for example, jp.zentransfer.io to always connect to Japan). This can be useful if you want to force a particular route or are testing connectivity to a specific node.

Monitoring and Status

All edge nodes are continuously monitored. You can check the real-time status of each node at status.zentransfer.io. The status page shows whether each regional server is operational, degraded, or experiencing an outage.

The servers run on a mix of infrastructure providers, primarily Azure and AWS, chosen per region based on availability and network performance. All nodes run the same codebase deployed from the same repository, ensuring consistent behavior everywhere. All servers are automatically patched regularly with software and security updates, and monitored through a single pane of glass so we can quickly remedy any issues.

What About Regions Not Listed?

We evaluate new regions continuously and respond to customer demand. If you regularly work in an area that is far from any of our current nodes, let us know. Adding a new edge node is a straightforward process, and user feedback directly influences where we expand next.

Getting Started

To use the global FTP network, simply configure your camera or FTP client with ftp.zentransfer.io as the host. You will automatically be connected to your nearest edge node. No region selection or additional configuration required.

If you are not yet a ZenTransfer user, sign up at zentransfer.io to get your credentials.
