Consider distance and workload separately
Tokyo network reference
The average latency reference for connections from East Asia is 30~60ms. Use this as a guide when choosing a location, not as a fixed measurement for every route or a promise of desktop frame rate or file transfer speed.

Connection quality to the same node can vary between team members. SSH command-line interaction is mainly affected by round-trip latency. A graphical desktop is also affected by resolution, on-screen activity, and available bandwidth. Builds run on the physical node, so a slower local connection won’t move the workload to your computer.
Test your actual work network in three ways: run a series of SSH commands, open a desktop app you use regularly, and sync a representative project. Track the initial dependency fetch separately from subsequent incremental builds so that cold-cache download time isn’t mistaken for machine performance.
Test your connection after delivery
Replace the hostname in the commands with the connection address in your order details. Some networks restrict ICMP, so no ping response doesn’t necessarily mean SSH is unavailable. Check the connection using the relevant port and your client logs.
ping -c 20 NODE_HOST
ssh -o ConnectTimeout=10 USER@NODE_HOST 'uname -m'
