Hello,
I've been checking your suspension logs, and you have been suspended 3 times in the last 3 days for high resource usage. I've also had a look at your site, and see you are using Wordpress. You may want to disable any caching plugins you may have, as they often consume a lot of CPU etc. Also, any image resizing plugins may be best disabled for the time being. If the problem persists, you may want to consider an upgrade to Prime, Illuminated or Premium.
