VirMach uses custom systems to ensure the best quality of service for all our customers. These systems enforce our Acceptable Usage Policy to save time and reduce cost dealing with abuse. They also ensure that abuse is dealt with in a timely manner in most cases. Below is an outline of our automated anti-abuse systems.
CPU Watcher
Our system scans and averages out CPU usage per VM. Based on an algorithm, customer’s VPS is added to a grey-list if customer surpasses the threshold of acceptable usage. After multiple offenses, you are warned. If abuse continues, customer’s service may be powered off or suspended. If the customer has the “high/dedicated CPU” addon, the script ignores the customer’s usage.
I/O Watcher
Our system scans and averages out I/O usage per VM. Based on an algorithm, customer’s VPS is added to a grey-list if customer surpasses the threshold of acceptable usage. After multiple offenses, you are warned. If abuse continues, customer’s service may be powered off or suspended. If the customer has the “high I/O” addon, customer’s threshold will be doubled. The threshold varies by package. The larger your share of disk space, the larger your share of I/O.
Network Monitor
Our network monitor script ensures we keep our network clean of malicious traffic. If you surpass a certain amount of conntrack sessions, are suspected of sending or receiving a denial of service attack, suspected of bruteforcing or being attacked, and/or have malware on your service, customer may be warned or have their service interrupted or suspended.
Nullroutes
Nullroutes occur in cases of inbound attacks, sending large number of SMTP packets, having a bad e-mail reputation, and/or receiving a DMCA notice or blacklisting of IP. In most cases, nullroutes will automatically expire. We will try our best to notify customers of these nullroutes, which are performed by the datacenter. When a nullroute occurs, your public IP is unavailable but your service is active and can be used through your control panel’s VNC and console features.
