Guild Wars 2

I keep getting this error : Guild Wars 2 has encounter an error. It started around 1am 03/23/2015. I can’t purchase items in the black lion market because the error pops up. I tried to do something else, … so, right in the middle of my personal story GW2 has encountered an error and could not save you progress. It is 2:52am that is the problem

Servers have crashed by the looks of it. Nothing you can do until they come back up.
