They're updating for me. Is there a specific problem that you're having that's not letting you see the statistics? It would be great if you could elaborate on your problem.
It stuck to $811 for me and not updating!
That's weird, thanks for pointing it out. I didn't even notice because I was looking at the graph.
Like someone above said, you can contact blockchain.info to get it fixed. Another solution would be to maybe raise awareness in the trollbox, as it seems that people don't seem to be too bothered as long as the graph is working. The more the community wants it fixed, the faster blockchain.info will get it fixed.
