What Happened to Hacker News RSS

I'm subscribed to HN hnrss.org/newest?points=100 via The Old Reader[1] but today I stopped receiving the newest articles. I tried to manually refresh the feed via the refresh button but again no new articles. I tried to subscribe via Feedly[2] to rule out a problem with The Old Reader but there also the latest articles are a day old. I tried without points constraint with the hnrss.org/newest URL in both readers and the result was the same. All day-old articles but without new ones.
