Case #1: Athens Olympics Network

unique project is that the athletes aren’t
going to stop running just because the
server does.
• Major Components:
• Games Management System (GMS)
• Information Diffusion System (IDS)

Case #1: Athens Olympics Network
Fail-Safe Plan:
• Redundancy
• Constructed the network in such a way that
service could be provided even if one of the
routers was damaged.
• Stored data in two physically distant data
centers (in different earthquake zones).

• Test. Test. Test. “We wanted to be sure
that every stupid thing that can happen
was planned for.”

Case #1: Athens Olympics Network

success without all of the networks and

backup technologies?
2. How would your 2004 Olympics experience
changed without the GMS and IDS systems?
3. The 2004 Olympics is a global business. Can
a business today succeed without information
technology? Why or why not?

Case #1: Athens Olympics Network
4. Claude Philipps said dealing with the
“crazy scenarios of what might happen
in every area: a network problem, staff
stopped in a traffic jam, a security
attack… everything that might happen,”
was the reason for so much testing.
Can you think of other businesses that
would require “crazy scenario” testing?
Explain.

systems in place limited to one-time
