Set up a wordpress page the other day following this guide. The site was up and running, loading quickly and all was well, until today.

Suddenly, loading the site takes forever and doesn't even work properly, the page shows up in an incomplete fashion.

I tried rebooting the instance but that didn't help.

The only actions I've taken on the server is to create an elastic IP, and to point a domainname to that IP. But I don't see how that could've slowed down the page.

Any thoughts on what could have caused this and on a solution to the problem?
