The first thing to do is check the switchboard. Do you have fuses or circuit breakers?
If you have a circuit breaker switch, it may be as simple as flicking this switch back on. If this does not work, call your electrician.
If the switch is still on, try checking outside or with neighbors. Maybe the power outage is due to an electrical supply problem for your area. If this is the case, call your local supplier.
