We've had similar problems with another platform in China -
PROBLEMS
Low level networking parts of platform blocked or not accessible in China due to firewall
Access to platform was noticeably slower due to additional restrictions and routing hops that traffic goes through in China
SOLUTIONS
Reroute traffic to WAN (Wide Area Network ) inside PLT to increase speed for internal users
Whitelist/Reroute Proxy List of IPs (Internet Protocols) for all in service hosts including third party IPs associated with platform (i.e. CDN)
Another third party, could not provide an Proxy List of IP Addresses, but gave us a domain list instead
Share full URLs to allow external partners to access content via Gallery-Bit.ly blocked in China
