The BeiingAir automatic Twitter feed is stuck at 6/2, 4:00pm, just before Twitter was blocked in China.
I'm working on some analysis for another post related to the BeijingAir Twitter feed, which automatically tweets hourly PM2.5 concentrations at a single station in Beijing.
In looking at the data just now, though, I realized that it hasn't updated since June 2nd at 4:00pm, shortly before Twitter was harmonized in China.
It may be just a robotic scientific instrument (a Met One Bam 1020), but don't you think it still had its feelings hurt? Let's all hope for a prompt release of Twitter so Bam can get back to doing what it does best.
Update 6/8/09: Twitter is back, and so is the feed:
Looks like Twitter was officially blocked for 5 days, 22 hours...
