Resource Abuse Policy Syfertek allows CGI, PHP, Perl and many other normal processes used for hosting to be used on all Virtual Servers. These processes can be resource intensive however, and because a Virtual Server must be shared with other users, we must limit how much of the CPU, memory, disk I/O, disk space and database use can be used by any one account on a shared server. Therefore any program (application, script, etc.) or usage that consumes too many resources that impacts other customers in either performance or reliability is considered resource abuse. Shared servers are 'shared' and we all need to play fair. In the event a user requires more resources than is acceptable on a shared server environment, a dedicated solution, such as our VPS, dedicated or colocation services are recommended.

What does Syfertek consider "System Resource ABUSE"?
Any site whose traffic, programs and/or processes are using excessive amounts of system resources. Excessive amounts is defined as any amount that results in substantial degradation of server performance. Syfertek is the sole determinant of what constitutes degraded server performance.

Examples include, but are not limited to:
  • Flat File Database Driven Forums. Due to their use of flat files instead of databases, Syfertek does not allow the use of UBB or YABB bulletin boards. Use of these boards for large or very active forums, results in system performance degradation, and cannot be allowed in our shared server environment. Syfertek suggests using VBulletin or phpBB as a more efficient, database-driven alternative to these bulletin boards. Busy sites with large forums and data bases are not suited to a shared server environment.
  • Background Running Processes. Background Daemons in general are prohibited on Syfertek servers, including, but not limited to, IRC bots, eggdrop, BitchX, XiRCON, warez sites and any other program that interferes with normal server operation.
  • Persistent mySQL Connections: Due to the fact that persistent mySQL connections have the ability to use considerable server resources, this configuration is not allowed on our shared servers. It is understood that in some situations, persistent connections may actually reduce resource usage on a server. However, we have found that connections are commonly not released properly and are, therefore, more detrimental to a shared hosting environment than they are helpful.
  • Cron Jobs. We allow customers to set up cron jobs to perform routine functions automatically. Due to the impact on the server, running some automated processes can take up considerable server resources and in those cases, our technicians may disable the cron job.
  • Mailing Lists. We have a strict policy regarding use/spam on our network, but we do allow use of mailing lists within the constraints of our spam policy. However, sending thousands of e-mails off of a given server can impact the performance of the server. Therefore we limit the amount of e-mail allowed on our Shared Virtual Servers (including the Bulk Reseller servers) to no more than 1000 e-mails per day and 30 emails in 10 seconds.
  • Exploitable Scripts. Unfortunately, many commonly used scripts can be exploited to allow unauthorized users into our systems. Consequently we may on occasion need to ban and consequently disable these scripts. You can view the most current exploits on our banned-scripts page.
  • Other. Other resource intensive scripts (depending on traffic) include but not limited to: adcycle. Other applications that are prohibited on our virtual servers include but are not limited to: offsite search engines.

Why does Syfertek have this policy?
Server Speed and Fairness to others. A Virtual Server is shared. As such, there are many accounts per machine. In all fairness, Syfertek cannot allow one or two clients to use all of the System resources on a shared machine and have all other clients on the machine suffer because of it. Excessive usage by one or more clients causes extreme slowness in all areas: FTP, SSH, Web Sites and more. If the CPU, disk I/O and/or memory usage gets too far out of hand, all sites hosted on the machine will return Errors and not be accessible in any way.

What happens if I violate this policy?
All accounts that are found to be using excessive amounts of system resources will receive an e-mail warning from Syfertek. This warning will inform you that the site is using excessive system resources. Syfertek will provide options for reducing the usage and/or upgrading your account. If the situation is severe, we may suspend the account or process immediately to bring performance of the server back to an acceptable level. 24 hours notice will be given if at all possible.
