How will I know when I exceed the allowed bandwidth for my Wix site?
There's no need to worry about exceeding the allowed bandwidth. We will warn you if you are getting close to this limit. There are no consequences prior to the first warning.
Note: The unlimited bandwidth and storage options are intended for the very high traffic sites that have a high usage of media assets. In most cases, a site will not exceed the bandwidth and storage limitations.
In the future, we intend to add a counter which will enable users to check their bandwidth usage for themselves. We will notify our users once it's ready for use.
