One of the best things you can do to avoid or fix the 509 bandwidth limit exceeded error is to turn on CDN Caching.

CDN or Content Delivery Network is a network of servers, distributed over various locations around the world, which delivers web content to the user based on their geographic location, the origin of the web page and a content delivery server.

Generally, the browsers request all the website content from the server, whenever a user is trying to access the website through the browser. This process is responsible for increasing the rate of bandwidth usage.

Hotlinking is like someone has embedded or used a link or URL on their website and that URL directs to a media that is hosted on your server. So, whenever a user clicks on that particular link, it will start consuming your server resources.
