Your hosting account uses bandwidth when it sends or receives data with the rest of the Internet. For example, if your hosting account contains a 1MB picture, and 2,000 visitors view the picture, it uses 2,000MB (2GB) of bandwidth.
You can check how much bandwidth your account has used, as well as its monthly limit, at any time.
Your bandwidth limit and usage display in the Account Snapshot area.
If you want to change your hosting account's bandwidth limit, see Upgrading or Downgrading Your Hosting Account.
