Flash-cut
From Wikipedia, the free encyclopedia
A flash-cut is an immediate change in a complex system, with no phase-in period.
Some telephone area codes were split immediately, rather than being phased in with a permissive dialing period. An example is telephone area code 213, which was split into 213 and 714 all at once. Another example is an immediate switch from an analog television channel to a digital television channel, such as WGNM or W39CO.
A flash-cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period.
