Switch > Connection Test

Nintendo provides three connection test servers for the Nintendo Switch:

The first server is used to check if the internet connection is working when you connect to a wifi network. The next two are used to measure your download and upload speed.

The last server was introduced in system version 18.0.0 and is a replacement for /v1/time of the AAuth server.
