We were notified by the service running our proxy for www.skritter.cn that they are doing an urgent migration to improve stability. It will be from 25-Aug-2011 23:00 to 26-Aug-2011 01:00 (+800) Hong Kong Time. During that time their services, and so by extension www.skritter.cn, will be experiencing brief interruptions and short-term instability. We'll keep an eye on things and make sure www.skritter.cn is running smoothly after this.

www.skritter.com will be unaffected.

Didn't notice a hitch, and everything has been working fine for me on the mainland today.

Generally, I think you guys do a great job and I've got to say that this is easily among the best study aids I've found in my years of learning Chinese. I very much hope the service never gets blocked here on the mainland.
