Clearance server deals are promotions and sales by web hosts to sell low end or old servers at a discount to customers. Clearance servers have different configurations that will vary and differ from web hosts to web hosts. Don’t expect to find the same server configuration being marked as a clearance server from two different web hosts.
When web hosts offer clearance servers, the servers may feature processors (CPU) that may be a few years old or from one CPU generation ago. The server may feature low end specifications like a slow processor, not a lot memory, or a non SSD hard drive. The specs for different clearance servers may vary but they typically do not include the latest technology or more resources. Web hosts offer clearance server deals to help sell these servers to those that may need a spare server that doesn’t require a lot of power or for customers that want to save a lot of money for a dedicated server.
