Well, where do you see it reboots 10 times in less than one month?
I just see "Last reboot: unknown".
If you're saying the "hosting history", you can see the IP address alternates,
suggesting that it only suggest when it's IP address changes.
Actually, unless with active monitoring, I can't see there're some way to record whether
a server has been rebooted, and there're tools like "kexec" that allow a reboot in Linux
complete in a short time. (My Linux server, which runs MySQL and Apache, reboots with
downtime within 2 minute)
