Resource Abuse Policy


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 shared system resources is a serious problem. Accounts on a shared server must share resources 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.

AVERAGE SERVER RESOURCE LIMITS

Memory usage may not exceed 10% per domain/file/application
CPU usage may not exceed 20% per domain/file/application
Apache connections may not exceed 30 connections
15 MySQL maximum user connections allowed
350 emails per hour, per domain

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.

SUSPENSIONS

In the event your website has been suspended for resource abuse (abuse that cannot be resolved by removing/changing a script, etc.) and you do not wish to upgrade to a dedicated server to accommodate your site needs, we will only release the suspension within 24-48 hours. This is to ensure the CPU intensive site slows down in traffic to avoid further damage and problems. A backup will then be provided of your files or you will be allowed FTP/cPanel access for a certain time period. Any questions about our abuse policy may be answered by opening a ticket with our abuse division. You may visit the helpdesk by clicking here.

Inodes

Accounts on any shared hosting account may not have an excessive number of inodes. Any account found to have over 100,000 inodes may be removed from our backup system to prevent overload. Any account seen to be exceeding 250,000 inodes is at risk for suspension. A warning will be sent and if no action is taken to resolve the issue, the account may be suspended. Every file on the account is counted as 1 inode. This includes mail as well as webpage content.

Cron

We allow customers to set up cron jobs to perform routine functions automatically. Any client who schedules cron jobs in such a manner that jobs take more then half the time to complete before the next scheduled iteration, and more frequently then 10 minutes is abusing the cron system. Any automated processes that excessively consume resources and impact server stability may be disabled at our discretion by our technicians.

VPS SERVICES

In order to control the VPS hardware node and to ensure that no single VPS account monopolizes the shared hardware resources of the VPS node (CPU/RAM) we use virtual limits to implement certain controls. The limits, or barriers if you will, which are most strictly enforced are the process limits (numproc), the RAM limits, and CPU usage limits. The ‘numproc’ limit which does not actually correlate directly with the number of processes you spawn, rather the number of kernel level threads any VPS account spawns is how the limit of kernel level processes are controlled. Please see below for the specified limits.

Numproc Limits
VPS-STARTER – 180:180
VPS-STANDARD – 220:220
VPS-PREMIUM – 260:260
VPS-ADVANCED – 300:300

We strictly limit the amount of RAM that each account is given. With any account, your account may only use the amount of RAM which is guaranteed to your VPS.

VPS Memory Limits
VPS-STARTER – 512MB
VPS-STANDARD – 1024MB
VPS-PREMIUM – 2048MB
VPS-ADVANCED – 4096MB

Our VPS offer an equal share of CPU to all accounts sharing the hardware node. With this given, the CPU limits are as follow:
CPU Usage Limits – 700MHz Guaranteed, burstable to 850MHz

Any single VPS account which is surpassing the above limitations is considered “Abusive”. Should your VPS be abusive for more than 12 hours you will be at risk of suspension. BusyRack.com reserves the right to suspend, without prior notice, any VPS account which is causing the main hardware node.
