What possible causes are there for an ACPI power button event?

What reasons could there be for the ACPI power button event being triggered, other than someone pressing the power button on a server?

I have a CentOS 4 server in a colocation facility, which recently shut down without an admin initiating the shutdown. After some investigation, I found the following in acpid's log:

acpid:[Sun Mar 1 05:06:48 2009] received event "button/power PWRF 00000080 00000001"
acpid:[Sun Mar 1 05:06:48 2009] executing action "/sbin/shutdown -h now"
acpid:[Sun Mar 1 05:06:48 2009] BEGIN HANDLER MESSAGES
acpid:[Sun Mar 1 05:06:48 2009] END HANDLER MESSAGES
acpid:[Sun Mar 1 05:06:48 2009] action exited with status 0
acpid:[Sun Mar 1 05:06:48 2009] completed event "button/power PWRF 00000080 00000001"
acpid:[Sun Mar 1 05:06:51 2009] exiting

This seems to indicate to me that someone in our colocation provider's datacenter accidentally shut down our server by pressing the power button. However, they say that none of their staff were in that part of their datacenter at the time the server was shut down. I've done some searching and I've been unable to find any other causes for this event, besides it showing up sometimes when restoring from suspend or hibernation (which this server was definitely not doing).

I'm a little dubious of their explanation, but I'd like to have some evidence to back me up before I talk to them again. So, my question is - is there anything besides someone pressing the power button on the server that will trigger the button/power ACPI event?

Who is your provider? Are they using remote console cards? I think those would use ACPI to initiate a hardware shutdown/reboot. It might also be something related to a UPS failure triggering safe-shutdown scripts.

Response by poster: My provider is ServerBeach. They provide a "RapidReboot" service in their web interface, which I imagine might use a remote console card.

Thanks for your help.
