-8 in downvotes with no explanation? really guys? Sorry for trying to help, i'm out.

I was on EC2+apache+wordpress+mysql and had my blog go down as well after being featured on HN. In my case, simply rebooting the cloud instance fixed the problem (I had lots of other old projects running on the same instance). However, I did do some research into figuring out what I could have done as my blog kept getting more traffic ... had I used RDS, I could have gone to a bigger instance with little downtime. Unfortunately, my understanding is that there would be no way to go back down to a smaller RDS instance.

P.S. I upvoted you. I also don't get why people downvoted you.

I also upvoted you for the helpful post. However, you aren't supposed to use caps for emphasis on HN. That could be the reason.

It's probably not what you said, but how you said it. It's tone is more confrontational than informative - and that's really just the first few words.
