The recent weather tragedies we have suffered weren't to blame. My house burned to the ground on June 26, 2012 and now that we're back, we have upgraded to a higher internet speed.
My guess, after a few hours it started working fine again...after the morning hours on a Saturday when many of us like to take a break and play, it was extremely slow. Too many users at one time caused the site to slow down, like my wi-fi does at my house when my TV is streaming and my sons are gaming on the internet. When people started logging off Guitar Tricks to go about their day, my connection speed got much faster. Thus, my take on the problem.
