Scary: Mostly insiginificant earthquake knocks out cellphone coverage in Los Angeles

You may have heard that there was a 5.4 earthquake in Los Angeles around lunchtime It caused almost no significant damage, and no damage to the cellphone service providers. But cellphone usage spiked enough to disrupt cellphone service (my Verizon phone showed full bars, but calls simply didn't go through). A disturbing reminder of how unprepared companies are for emergencies.
