Growth Hacker Marketing, by Ryan Holiday (excerpt)

The system had major technical problems during Election Day that
prevented many volunteers from using it. It crashed periodically and
at one point was intentionally taken down when a surge of traffic from
campaign volunteers was misinterpreted as a denial of service attack.
Frustrated volunteers reported being unable to access ORCA and
criticised a lack of prior briefing, misleading instructions and
patchy on-the-day support. A Romney aide commented that “Orca is lying
on the beach with a harpoon in it.” The system’s failings have been
attributed by technology writers to a combination of factors including
not doing prior quality assurance or beta testing, inadequate
documentation and poor design.
