Your company is worried about instability in the electrical power provider it uses. Occasionally voltage dips below expected levels causing issues for computing infrastructure. What term defines this situation?
A brownout is when voltage drops suddenly below the expected levels causing intermittent issues for electrical devices. A power surge is the opposite (increase in power) and a blackout is a total loss of power.
A brownout is an intentional or unintentional drop in voltage in an electrical power supply system. Intentional brownouts are used for load reduction in an emergency. The term brownout comes from the dimming of incandescent lighting when the voltage reduces. A voltage reduction may be an effect of disruption of an electrical grid, or may occasionally be imposed in an effort to reduce load and prevent a power outage, known as a blackout. Brownouts can also stem from an excessive demand in electricity or when severe weather events occur.In some countries, the term brownout refers not to a drop in voltage but to an intentional or unintentional power outage (or blackout).
