[ih] Origination date for the Internet

Per Farooq Hussein's account, the CIX initially used a Cisco AGS 
initially. See page 6 of 

He says it's currently at the Equinix office in Reston. The 7500 that 
replaced the AGS after it was moved to Santa Clara is now in the 
Smithsonian. It would be a fun field trip to go see them.
