Any website on our shared servers that uses a high amount of server resources (CPU, memory usage, and network resources) will be given an option to pay for a dedicated server. The abuse and misuse of system resources is a serious problem, and AHosting does not tolerate it. Accounts on a shared server must be shared with other users, so we must limit how much of the CPU and memory that can be used by any one account.
In all fairness, we cannot allow one or two clients to use all of the system resources on a shared machine and have all other clients suffer because of it. Excessive CPU & memory usage by one or more clients causes extreme slowness in all areas: MySQL, Email, HTTP and more. If the CPU & memory usage by a few clients gets out of hand, all sites hosted on the machine will return errors and not be accessible in any way.
There are special exceptions to these rules to be determined at the time we discover abuse. There are different combinations of usage that can create problems and other special cases. At any given time a server is unstable and an account is found to be the cause, we reserve the right to suspend the account to keep the server online and operating normally. If the usage is an increasing trend, we recommend the user invest in a dedicated server so the website can grow at a normal rate without restriction.
