Hello.

Even if you exceed the amount of data used in your Lightsail plan, your data will not be interrupted.
However, you will be charged for the excess amount.

Q: What types of data transfer do I get charged for?

When you exceed the monthly free data transfer allowance of your instance plan, you will get charged for data transfer OUT from a Lightsail instance to the Internet or to another AWS Region or to AWS resources in the same Region when using public IP addresses. The charge for these types of data transfer above the free allowance is as follows:

• US East (N. Virginia): $0.09 USD/GB
• US East (Ohio): $0.09 USD/GB
• US West (Oregon): $0.09 USD/GB
• Canada (Central): $0.09 USD/GB
• Europe (Frankfurt): $0.09 USD/GB
• Europe (Ireland): $0.09 USD/GB
• Europe (London): $0.09 USD/GB
• Europe (Paris): $0.09 USD/GB
• Europe (Stockholm): $0.09 USD/GB
• Asia Pacific (Mumbai): $0.13 USD/GB
• Asia Pacific (Singapore): $0.12 USD/GB
• Asia Pacific (Sydney): $0.17 USD/GB
• Asia Pacific (Tokyo): $0.14 USD/GB

  Instances created in different Availability Zones can communicate between zones privately and for free, and are much less likely to be impaired concurrently. Availability Zones enable you to build highly available applications and websites without increasing the cost of data transfer or compromising your application's security.
