Your net code is absolute trash

cut the crap blizz and be transparent with your customers, post your issues in your forums, not everyone follows twitter. your net code is next to my trash cans sitting in the street

The post they made on October 14, that is stickied at the top of this forum, about the connection problems names the net code as the primary issue.
They said so themselves.

Hes clearly frustrated, reading the sticky and having time to calm down and have a rational thought gets in the way of rage posting.
