Faisal, what happened this time? The network appears to have taken a dive at 12:31 and never recovered as far as I can see (though I just was scanning my logs).
One of our Redback Routers, decided that it did not like the flowers that were sent to it for Valentine's Day. As such was not in a good mood. Had to be gently persuaded, we offered chocolates and cheesecake, it finally came around.
