How it works

The internet connection checks, implemented in the AWS Lambda function, can be triggered in two ways:

• automatically: through the AWS EventBridge, specifying a rate interval (like a cron job)
• manually: invoking a REST Api exposed by AWS API Gateway (this API is public! It should be better protect it with AWS IAM)
