As far as I know:
1.Tidis due to server load balancing, which was mentioned in last CSM minutes.
2.A few translations are not the most appropriate for the context, for example the names of conduits in Abyssal space level 3 and higher:
Proving Conduit–安全导管(which also means“Safe Conduit”)
Origin Conduit–初始导管
In my opinion I would use 起点导管 for Origin Conduit and 试炼导管 for Proving Conduit respectively.
I had seen multiple posts of newbies getting popped for choosing the “safe” conduit since Serenity relaunched.

I know you can see PVP in the description just by right click and “show info”, but that is just too demanding for newbies.
3.Certain ceontent are blocked by GFW similar to the way of Russians got blocked from chat server.
In the Tiancity era they used to drop Project Discovery on Serenity bceause the web host of test images is somehow blocked by GFW. I don’t think there’s anything offending in the content and it’s just the rules being erratic. I’d hope CCP at least try to respond to such issues and host contents in non-blocked places if possible.
