Beijing: where is the air quality report?

I often check the air quality report. It is a kind of game for me.
Can I guess the today's level? Was it level 2 or worse?
It is difficult to tell. The sky might be perfectly blue, the sun shines and you do not think bad, but then you check the air quality report and you are surprised that it was an unhealthy day.

I appreciated the openness of the government to publish these data. However since some days... "Sorry, no record". (normally you should get the data with that link)

So why that? Is the air that bad?
Why am I assuming the worst? Because we experienced before: bad air quality on certain days result in no data. I wrote a blog post about that here after the car reduction test in August.

Let's have a cup of tea and wait. It does not look that bad these days.
