Google mail service Gmail has reportedly been blocked by China’s Great Firewall following months of disruption, an anti-censorship group said Monday. GreatFire.org said many Gmail users were cut off in China on Friday and services were still down Monday. “We’ve checked and there’s nothing wrong on our end,” a Google spokesman in Singapore said in an email. Google’s Transparency Report, which displays Google’s real-time traffic, revealed a sharp decrease in traffic in China on Friday. While Google users have experienced disruption since June, Gmail users could still access emails downloaded via protocols such as IMAP, SMTP, and POP3. Chinese Foreign Ministry spokeswoman Hua Chunying said she was unaware of any block of Gmail services, noting that the government was supportive of foreign investors and businesses.
