Note at 0227 UTC on June 21st: These A/CC news pages did not update for the remainder (most of) June 20th, and not until early on the 21st. Our caching system for tracking risk pages became accidentally scrambled and the first attempt at restoration only made things worse, so we stopped all automated news processing until the situation was understood and repaired. Fortunately no data appears to have been lost, just a lot of time. Our apologies for the outage. Please note that today's impact risk rating changes are reported according to when A/CC actually recorded them, which is on Monday the 21st
