Anyone experiencing latency spikes and disconnections?

W0x9 or similar error popped 3 times already within 2 hours. Once during a guardian raid and another one during chaos dungeon. Lost aura of resonance on one of my character.

I checked my internet when this error occurred and things are fine. Have no idea what the error code is about, any idea on the root cause??

It never happened this often before and I notice the in-game latency is spiking up and down crazily just TODAY during instance runs (up to 1000ms+ which never happened before). Asked a teammate during a guardian raid run and he is experiencing the same.

Living in the east coast and server is US east - Una.

Any help?
