I am facing a strange issue where one of our servers (used for internal purpose) hosted by Rackspace uses huge amount of bandwidth (but our actual users are using the server rarely).
FYI, the said server was compromised once, serving landing pages for phishing websites. At present we have removed all those landing pages and the server is clean now. But Apache error logs points to those (now non-existing ) landing pages.
My question is does 404 error pages use lot of bandwidth ? How can we avoid this situation ?
Thanks In Advance.
