Odd lag

[Sulta]

The last few days I have had periods of odd lag. I thought it was on my side after watching the forums and not seeing anyone else mentioning it... I've got a decent computer a more than fast enough internet connection...I've restarted my computer and internet just in case but that didn't help. It has also appeared while on 2 different computers. I'm wondering what else I can do to try and figure out this problem...see I'm not very computer/tech savvy, but I figure since it's something new there has to be something I can do to get back to a pre-laggy state?

Any ideas or help would be appreciated!
