What are some common internet challenges for foreign companies in China?

Due to the Golden Shield Project in China, it is difficult for companies to access non-domestic websites. Internet speed is slow, connections are unstable and latency is high and technically, since there is a very small network bandwidth with China and countries overseas, foreign companies are also finding it even harder to transfer real-time data. A lot of popular services that are not available in China have a huge impact on foreign companies, especially those that rely on these services.
