We try to work with our clients to avoid the need to suspend sites as it can be an embarrassment to a webmaster. If we cannot elicit a response from you we may be forced to do so. Sometimes this is because your site has been exploited or is over using resources to the detriment of other clients. Billing issues rarely result in suspension - we send out numerous notices beforehand.
Note:- cPanel does automatically suspend sites that exceed their traffic allowance. Be sure to enter a valid, off server email address in the control panel and you will be warned that your allocated bandwidth is being used - contact us and we'll help you to resolve the issue.
Finally, please ensure you comply with our Terms of Service, especially copyright and abuse issues as we have to work quickly on these matters or our providers will simply unplug the server.
