Google on Tuesday unveiled a traffic tracking tool that will let users see if traffic disruptions are due to technical issues or a government ban.

The site will replace the Mainland China service availability chart Google launched in the wake of its decision to stop censoring search results in the country.

The tool includes a drop-down menu of 125 countries next to a drop-down menu of 17 Google services, like YouTube, Gmail, and Google Search. Match a country with a Google service, and Google will display a graph with the traffic for that service in the region. If a service is blocked or has been blocked in the past, Google will include a note. YouTube for example, has been blocked in Iran since June 12 and was blocked in Pakistan for 10 days in the wake of "Draw Mohammad Day."

"By showing outages, the traffic graphs visualize disruptions in the free flow of information, whether it's a government blocking information or a cable being cut," David Drummond, Google's chief legal officer, wrote in a blog post.

Also on Tuesday, Google added data from the first six months of 2010 to its government requests "Transparency Report" tool. The Web site, launched in April, provides information about the number of government inquiries Google has received for information about users or requests for Google to take down or censor content.

"We've also updated our analysis of the trends we saw across the data over the past six months," Drummond wrote. "The new data for 2010 now includes the number of individual items asked to be removed, per country."

In the United States, for example, Google has fielded 4,287 data requests from January to June 2010. Of those, 128 were removal requests. Google said it complied fully or partially with 82.8 percent of the removal requests.

"We view this as a concrete step that, we hope, will encourage both companies and governments to be similarly transparent," Drummond said.
