From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Compare some of 3Com's, Cabletron's, and Cisco's oldest products with those the vendors offer today.
By Suzanne Gaspar
Network World, 03/26/01
To
see just how far network gear has come over the years, consider what
functionality your money would buy in 1986 and compare it to what
you'd get today.
Star topologies and wiring hubs arrived on the scene in the late 1980s, making networks affordable, more reliable and easier to administer. Thanks to 1990's IEEE 10Base-T standard for Ethernet over unshielded-twisted pair wiring, the price of hubs and network interface cards (NIC) dropped dramatically. A switched port that used to cost more than $2,500 costs less than $50 today, giving IT professionals more flexibility in designing their networks.
The explosion of Internet commerce and mobile access is driving demand for higher capacity and faster connections. Fortunately, widespread deployment of NICs, routers and switches brings higher speeds at lower costs, along with enhancements such as encryption, fault tolerance and load balancing.
Here's how the specifications and pricing of 15-year-old products 3Com, Cabletron/Enterasys and Cisco stack up to the vendors' current wares.
