If your internet access is out, it could be that a circuit breaker was tripped during a storm.
The New York Stock Exchange instituted circuit breakers to reduce volatility and promote investor confidence.
»There are three circuit-breaker thresholds—10%, 20%, and 30%— calculated at the beginning of each quarter.
After an index has fallen a certain percentage, the exchange might activate trading halts or restrictions on program trading. For example, if the Dow Jones Industrial Average falls by 10%, the NYSE might halt market trading for one hour. There are other circuit breakers for 20% and 30% falls.
