Gmail is blocked in China after months of trouble, with some pointing to the "Great Firewall" as reported by Reuters.
Large number of addresses gmail were blocked in China on Friday, according to GreatFire.org, a China-based freedom of expression organization. According to users, the service is still down today, Monday.
"I think the government is just trying to further reduce Google's presence in China and weaken its overseas markets," said a member of GreatFire.org, who uses a pseudonym. "Imagine Gmail users not being able to reach Chinese customers. "Many outside China will be forced to leave Google's email service."
Google Transparency Report, which shows real-time traffic to Google services, showed a sharp drop in Gmail traffic from China on Friday. "We have carried out inspections and there is nothing wrong with us," a Google spokesman in Singapore said in an email.
Problems have plagued almost all Google services in China since June, but until last week Gmail users could see emails downloaded through protocols such as IMAP, SMTP and POP3.
It is recalled that the country has the most advanced Internet censorship mechanism in the world, also known as the "Great Firewall of China". Critics point to deliberate obstruction of foreign online services throughout the year with the aim of creating an Internet cut off from the rest of the world.
Earl Zmitzewski, its executive Dyn Research confirmed to Mashable that there was an "IP-level" block in Gmail. "China has a number of ways in which it can block material. "One of the most crude is just blocking an IP address, and when you do that, you block all the material available on the IP," he said.
