^ After the first boss

Entire group got dc`ed from Artifacts from the past 8/8/14 @ 12:11am

When we where on the last boss he was Half life

Same thing happened to us 2 times on last boss 08:11 and 10:11 PDT, everyone in the instance got Kicked out, rest of the league was fine.

Same thing last boss of artifacts entire raid dc'd

maybe something was going wrong after the yesterday's hotfix.the last boss was bugged.
we were all exp players and (4 me at least) was not the first time.the first time we've been at the last boss 2 hours and after this time all the group was disconnected.too many mobs,the AW was impossible to grab.stucked on the vendor for repair the gear.

the space around the final boss was entirely surrounded by beams of white light .how result the whole group was fighting in a very small space with all the mobs, the boss and the group.this happened only from yesterday.yesterday this raid was impossible to finish.
sorry for my english guys,i know it's not good.

Happened to my group today. Beat the 2nd boss and was getting ready to move on then DC'ed out of nowhere.
