View source for Excessive 404 errors causing IP address to be blocked

On our shared Linux cPanel servers, generating excessive "''404: File does not exist''" errors will result in the IP address of the visitor generating the errors to get temporarily blocked.  


The purpose for this temporary block is for performance and manageability of the server and your site.  Consider this:  Assume that one visitor generates the full number of ''404: File does not exist'' errors within a few minutes minutes and the site in question has 100 visitors over the course of the day.  That is 20,000 errors in one day getting logged.  So over the course of a month that is over 600,000 additional errors for the site being logged.  With no restrictions, a busy site with bad code generating multiple 404 errors could very well generate millions of errors being logged in a very short amount of time.  Now multiply that by the number of sites on the server.  As you can imagine, this can quickly cause the server error log to swell to an unmanageable size.
