None of these are “production servers” (i.e. I’m not losing money if they go down) and I’m not even sure if 5 minutes of “downtime” should even be considered “downtime.”
My home server went down because I was doing some Xtreme torrenting which consumed all the bandwidth for which I have been paying. (I was such a nerd I was monitoring it closely.)
This site went down because our hosting provider sucks. I’m not going to say who it is though, at least not yet.
I’m not sure why the other one went down though. It’s not doing anything, and the hosting company seemed pretty reliable. I’m going to set up a monitoring filter to run on google.com, to use as a baseline/control test.
Also, I’m going to be writing in here more. You have been warned.
And yes, “Enterprise” is referring to the starship, and not the car rental or Microsoft’s cash cow line of products.

So are the options in your gmail “AWOOGA” or “Netflix”? That doesn’t seem very comprehensive. I’m concerned.
