There is really no excuse for "accidentally" routing through Chinese servers for a service. To me the reasons are as shallow as Google's "error in algorithm".

Just recently YouTube "accidentally" deleted the account of a pro-democracy channel in Hong Kong with more than 600k subscribers [1]. Incidentally, this has never happened to pro-Chinese channels.
