Websites sometimes display the error message Bandwidth Limit Exceeded. This is because the bandwidth allocated to the hosting account has been used-up.
Please be informed that bandwidth gets consumed by the amount of traffic your website gets from your online visitors. In other words, bandwidth is the amount of data that can be transferred from your site to the users’ computer. A high traffic website will require lots of bandwidth. The only reason that you will receive a white screen Bandwidth Limit Exceeded message is because your bandwidth capacity has reached its limit. So please upgrade your package in order to resolve bandwidth issue.
Large file attachments sent to others via email, count towards your bandwidth usage too.
In a nutshell, every data that moves to or from your hosting account is measured and counts towards your bandwidth consumption.
