Internet has been a mess in China for the last couple of weeks. Internet is always an horror story without vpn in China btw, what I mean is VPN haven't been working well, hence the chinese authorities have been cracking down and trying to block them intensely.
First the anniversary of what never happened in a central Beijing square 30 years ago, and now the traffic jam of peaceful citizens in HK all rushing to the same flower shop have probably to do with it.
