Cant we get the admins to ban the trolls in this thread and get it back on topic?
On topic : Will is trying his best to figure it out, i have been in contact with him in PM trying to sort out the issues. I was the first to bring up this 6pm-8am latency issue. We have been checking out some options and he recently told me the network team is on it. It does not seem to be a shaping issue.
With my very limited technical experience, i would assume it can be some routing issue. Lets have the professionals look at it (aka their network team) and be patient. At least this is happening in an "off period" of wow before the expansion, u can start qq'ing extensively if the network is still like this in December. This being said, we are paying for a service that has gone to #($* in the last few weeks, but im confident they will sort it out.
Please continue this thread with constructive comments like when you experience the issue, tracerts of when it happens and which tunneling service, if any, u are using.
FYI, I normally like trolling, but not in this thread.
