It was supposed to be simple. Spin up two small AWS Lightsail instances, one in Tokyo (18.183.98.38), one in Seoul (43.201.19.231), both 2 vCPU / 2 GB / 60 GB / Ubuntu 24.04, and drop a Nezha probe on them to monitor the little fleet I run. Drop the key, chmod 600 the pem, write two aliases tokyo and seoul into ~/.ssh/config. An hour&rsquo;s work.
