Just recently Uptime Robot (the awesome service that I use to monitor my server's uptime) have released a new feature: Public status pages! Status pages appear to be free (for now), so I've gone and set one up. Now all of you can see what's up with my website if it's down.

They even allow you to point a (sub)domain at it too. I did this too, so you can visit my status page at status.starbeamrainbowlabs.com.
