My uptime stats have improved greatly with Bluehost.  Lunarpages clearly was having uptime issues, at least with the server I was on.  The stats are even worse than they appear for Lunarpages.  I switched about Sept 23, because it was so bad.  Since then, there have only been 2 failed attempts by Siteuptime.

What is odd is my Lunarpages Review did not show up on their site.  I gave them a fair, but negative review. It makes me think that the site may not be as objective as I had hoped.  This is really sad for the consumer if that is the case.  I emailed the owner to ask.

Additionally, Media Temple has had 100% uptime.  Although, I still hate Plesk.
