Borders.com returned to service Wednesday Feb. 4 at 10:28pm EST after a 15 minute outage.  The error code returned by Borders.com servers during the outage was, “503 – Service Unavailable.”

According to W3.org, the standards organization that governs the current HTTP standards, error 503 states,  “The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay.  The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection.”
