Yesterday Chinese users of the Google.cn search engine faced problems accessing results for normal terms such as “dog” or “home”. Although Google has redirected traffic to its uncensored servers in Hong Kong, internet users in mainland China still face the Great Firewall, which bans access to sites containing sensitive information. The glitch was caused by Google’s new coding which incorporated “gs_rfai” into certain search terms. The letters “RFA” was mistaken to be an acronym for Radio Free Asia, a site banned by the Great Firewall.
