Terrible lag on Lindblum tonight?

[Blayde]

Just trying to do leves and I am having a really difficult time. My S and R are around 40 each. I try to cast a spell, the cast bar pops up already filled, then about 10 seconds later the spell finally casts. Once it casts, i try to cast another and i will get "X can't be used at this time" about 4 or 5 times until a spell will cast. Enemies are also continuing to attack me after they appear dead on my screen. I am not having any other internet problems.

Is something going on with the server?
