So, the question: will I trust Ubuntu on an Internet-connected system? Nah.
Will I trust Ubuntu on a server? Er, please excuse me while I finishing laughing hysterically!
Use Debian or CentOS or any of those reasonably tested other distributions for your boxes, and when someone asks you to use Ubuntu, in the immortal words of Fancy Raygun, ``Just Say No!''.
Interesting. I had a similar rant on my blog last week and got a number of responses to the post, mostly asking me to remove the post.

While I do understand that I was using the alpha version of Ubuntu but the problems I have faced with it could have easily been detected during QA. I had the luxury of moving over the Debian since this system didn't have a lot of critical data and downtime wasn't an issue, but I can understand why you would want to move to debian/cent OS on your servers.
