Wikipedia, which suffered sharp dips in various indicators, such as the number of new users, the number of new articles, and the number of edits. In some cases, it took anywhere from 6 to 12 months in order to regain the stats from May 2004. On the other hand, on today's site, some of the articles are put under protection which may last for a month or more without any actions. Second block The second and less serious outage lasted between 23 and 27 September 2004. During this four-day period, access to Wikipedia was erratic or unavailable to some users in mainland China – this block was not comprehensive and some users in mainland China were never affected. The exact reason for the block is a mystery. Chinese Wikipedians once again prepared a written appeal to regional ISPs, but the block was lifted before the appeal was actually sent, for an unknown reason. Third block and temporary unblocks The third block began on 19 October 2005, and there was no indication as to whether this block was temporary or permanent, or what the reasons or causes for this block were. According to the status page currently maintained on the Chinese Wikipedia, the Florida and Korea servers were blocked, whereas the Paris and Amsterdam servers were not. Dozens of editors from across mainland China reported that they could only access Wikipedia using proxy servers, although there were isolated reports that some users could access Wikipedia without using a proxy. Most Chinese people were not able to connect to the site at all. During October and November 2006, it first appeared that the site was unblocked again. Many conflicting reports came from news outlets, bloggers, and Wikipedians, reporting a possible partial or full unblocking of Wikipedia. Some reports indicated a complete unblock; others suggested that some sensitive topics remained blocked, and yet others suggested that the Chinese Wikipedia was blocked whereas other-language versions were not. From 17 November onwards, the complete block was once again in place. On 15 June 2007, China lifted the block for several articles, only to then block an increasing number of articles. On 30 August 2007, all blocks were lifted, but then a block was placed on Wikipedia for all languages on 31 August 2007. As of 26 January 2008, all languages of Wikipedia were blocked, and as of 2 April 2008, the block was lifted. By
