A renewed zest for enforcing China’s Great Firewall has seen a series of sophisticated and large scale direct denial of service (DDoS) attacks in the country over the last month, including a six-day attack on GitHub, as well as the Chinese mirror site for the New York Times and GitHub repository GreatFire.org.

The attacks, while severe, appear to have taken the heat off leading VPN providers, who were directly attacked in this January. At the time, popular providers including Golden Frog and Astrill recorded deep packet inspection (DPI) of internet traffic to identify VPN protocols, as well as attacks blocking the IP address ranges of several VPN servers.

The attacks appear to have dropped off during the newest DDoS offensive however, with VPN providers claiming that no further attacks of the same degree have taken place since.
