Additional RAM in VPS
Additional physical memory can be added to any of the Linux VPS services we offer, including the top-end ones, consequently your Internet sites will work correctly all the time. The upgrade can be obtained both on the order page and within the billing area, so you could add it anytime you require it: before your server is prepared - if you know that your sites will require more memory, or after the server is functioning - if you notice that the default memory is not sufficient for all the Internet sites to function adequately. In the second scenario, the amount of RAM you order will be added to the existing configuration without any action required on your end and without any Virtual Private Server shutdown or restart, so there won't be any downtime for your Internet sites. The upgrade is supplied in increments of 128 MB and you'll be able to add as much memory as you need, because the physical servers provide sufficient system resources to enable the virtual servers to be upgraded considerably.
