EUC, Neria: Crashes on matchmaking content, now >60s pings

Seems something horrible is happening to at least Neria, EUC.

First people were crashing left & right when loading into (event) guardian raids.

Now zone chat seems to have died, characters are not moving any more and ping is at 75 seconds:

Correction, we’re at >100 130 seconds ping.

Same here on the server Slen. Ping above 50000 ms.
Black screen after I docked the ship.
I closed the game and now there is no server in the list.
