downtime

I have two server monitoring tools that check the uptime of my Ubuntu 10.04.1 LTS server. Over the last month both of these tools have reported the following outages:

Jan - 15mins: self recovery
Jan - 5 mins: self recovery
Feb - 15mins: I managed to be online when this happened and logged into my control panel to find that my server was shutdown. I manually restarted it only because I was online. I wonder if it would have restarted?

I have contacted my VPS provider (webbynode) who could not see any any problems with their VPS infrastructure for the February outage.

I have also checked the following log files to see if there are any anomalies that could be the cause of the outages; I am unable to see anything related to the server shutdown (Feb) in these logs:

/var/log/auth.log
/var/log/apache2/error.log
/var/log/syslog
/var/log/kern.log
/var/log/boot
/var/log/messages

Could anyone suggest any other things I should look out for, such as additional system logs?

I just added bootlogging through /etc/default/bootlogd
