Instance Lag

[Yuengling]

I've been severely hindered by this for about 3 days now.

I get spikes of no animation, other than me casting, that last for about 5 seconds a piece. I can continue to use skills as long as I know how much MP I have.

Then, the last 5-10 seconds I just missed play through very quickly.

The whole time it's happening, I'm holding a steady 50+ fps, which is my norm.

I thought I may have a overloaded switch/hub at my house perhaps, but I've done everything I could think of to rule it out with no luck.

Edit: I should probably add the it starts around 10pm EST, and happens ever 30-60 second in instances after that. Last night I actually noticed it outside of an instance a few times, which was a first.
