We ran a few ad hoc crawls, and found that an average search might take up to 40 minutes. We'll be running the crawl manually today and will try to cover most of the major and popular routes.
Yesterday's data showed that the most popular ones are Taiwan, Tianjin and Guangzhou. We will try to get this data up and will post immediately on Twitter for the updates.
More updates to follow. Follow flyous on twitter.
