Server Maintenance :  Regular scheduled maintenance for systems used by COOLSchool will occur twice every month on the second and fourth Fridays of the month and will last for 18 hours, from 6:00 p.m. Friday until noon Saturday, Pacific time. Though generally not the case, the activity may cause the system to be down at any time during the 18-hour period, and may affect access to courses, e-mail, and COOLSchool support. Please plan your work so that you are not caught by surprise.
