Why are the servers so slow right now?

Thankfully, I'm delighted by this post. I've been lagging constantly since I have been on the forum really. It's like it takes a while for a button to function (hover, activate, etc.) once my mouse is over it. It's really annoying, like I'm running on some horrible network with a bad computer. Also sometimes there is a white background on the whole screen when first loading a page, takes a bit to fully load sometimes.
