Tight seal Bing remains one of the few non-Chinese internet firms that still have their core products up and running in a country where Google and Facebook have long been unavailable.

Gmail DNS hijacking in China (China Unicom ADSL)

Of these issues, difficulties with DNS in China is a topic that deserves its own post — when the packets of a critical service like DNS routinely go missing, the impacts on the delivery of important applications can be enormous. The common issues of high packet loss and latency in China especially affect DNS because it generally employs the unreliable protocol UDP. When a UDP message is sent, there is no way to make sure that it successfully reaches its destination.

Since there is no concept of acknowledgement, retransmission or timeout, very often a UDP packet sent out onto the Chinese Internet is simply lost.

To brush up on the specific DNS tampering tactics employed by the system of censorship in China, read our post Deconstructing the Great Firewall of Chinawhich summarizes the range of techniques that make up the Great Firewall. As a result of high packet loss and high latency conditions, many of the China agents could not reach the Route 53 DNS name servers at all, after two tries with 3 second timeouts. Packet loss and latency are greatly improved relative to traffic traveling across the Great Firewall, but issues still frequently arise due to the turbulent nature of networks and censorship in China.

This example comes from a DNS Server test that sends test traffic from all of our China agents to all name servers serving up the A record for nytimes. To follow along with the analysis, explore the data in this share link.

The nytimes. The US agents are able to look up the correct IP address for the name server In contrast, the China agents fail miserably: on the far right, we see a variety of IP addresses that have been returned for the DNS lookup for dns-plx.

Our China agents received bogus records likely as a result of DNS cache poisoning or hijacking from within the Great Firewall, a set of techniques long studied by academic researchers. Once the agents received the spoofed DNS reply, they then sent traces off to these blocked IP addresses.

The traces were then of course terminated within Chinese ISPs that practice IP blockingwhich entails blackholing traffic destined for blacklisted IP addresses like the ones we see below.

The story is the same for the other name servers hosting the nytimes. We can see this when we look at the Server Metrics view that shows the mappings for the nytimes. While the US agents all receive the same set of four IP addresses beginning with The DNS records for nytimes.

Resolution time gives us some clues — notice that the resolution times for the China agents range from ms, while resolution times for the US agents range from ms. Keep in mind the target name server is located in Newark.

These impossibly low resolution times indicate that the spoofed mapping was served from somewhere within the Great Firewall, likely via local cache poisoning, which is more lightweight and generally much quicker than keyword-based DNS hijacking.

These conditions can change at the drop of a hat — with the political climate, new and evolving censorship policies and even with diurnal patterns and the time of day. To keep abreast of any changes that affect important records, use DNS Server and Trace tests to continuously monitor the state of your DNS records, including their availability, accuracy and resolution time.
