Is it just me, or has the site been really laggy lately? Half of the time, everything is smooth and fast. The other half of the time (especially during peak hours) the site takes forever to respond. Sometimes the site doesn't respond at all, and I'll have to try again later. This is while other websites on the internet are responding fine, so it can't be my internet. Am I the only one experiencing this? What's the deal?

Edit: When the site is really acting up, I receive the message "Error: MySQL server has gone away."
