On Tuesday, June 30, 2015 at 5:00pm Pacific Time, a leap second will be applied to the Coordinated Universal Time (UTC). Box has taken action to mitigate risks to the availability of the Box Service. We will be closely monitoring both before and after the leap second to respond quickly to any issues with such availability. Although we do not reasonably anticipate any material impact, should it be necessary, we will implement Scheduled Downtime between 5:00pm and 5:30pm Pacific Time on Tuesday, June 30, 2015.
