For one, you should mention on the front page a) 15 minute poll-times (then also say "with optional upgrades"), and b) multi-node checks to ensure you know when you are really down.
I'm trying it out. I love it so far.
Couple ideas for paid features:
- A chart showing uptime vs. downtime. I just like charts.
- Ability to display server details like host etc.
- Optional notifications via cell phone text
- Ability to auto-notify hosting service via email of the downtime.
Glad you're liking it. I have most of these features written down as possible improvements and/or premium features. But it's good to get some validation of my own crazy ideas.
I'm getting a lot of error notices of no response before five seconds, then immediate error resolved. Not sure what this indicates. As I'm just a designer, I don't know if this is a problem or not. I'm at the point where I ignore all the notices. So now if it did really go down I wouldn't believe it.
