This is a text description of failoverex1.gif, which is an image of a time line marked from 0 to 11 hours, with each hour shown at an equidistance from each other. Failovers occur at point A (0 hours), point B (4.5 hours), point C (5.5 hours), point D (7 hours), and point E (8 hours). A failover does not occur at point F (11 hours), because the failover threshold has been exceeded.

In addition, at point C, the failover timer was reset to 0, and the failover counter was reset to 1.
