Narrative:

Climbing through 25;000 ft observed blue arcing in lower left side of ca fwd window followed by a loud bang. The window had fractured over entire surface. Followed QRH procedures and determined inner layer was intact.immediately leveled at 26;000 ft and advised ATC of problem. Contacted dispatch and decision was made to divert to airport ZZZ. Descended to lower altitude to reduce differential pressure and proceeded to ZZZ for normal landing with first officer flying. No further difficulties encountered. Windshield heat shorted; but didn't have time to pull circuit breaker as per QRH.
