Thanks again!
From my experience, going from one to multiple monitoring nodes gets way more complicated than expected; make sure you have your timestamps across the nodes right, especially when you decide to go down with the interval to 1 minute or less.
Also, investing time in a testing setup where all scenarios can be tested paid off greatly. Having scripts covering all edge cases lets you sleep better when you have paying customers :-)
Good luck!
Do you think 15 minute interval is enough? I assume the checks are made from one network location only (can't find details on the about page), would anyone be confident of the results with such setup? Is there any re-check in case of failure? API access? Etc.
I think this service might be popular with amateur bloggers/website owners. I don't think it would satisfy businesses that consider downtime a profit loss. I think they might be looking for a bit more advanced solution.
P.S. I'm a bit biased here. Since I started my own website monitoring project it seems that everyone else and their dog are also running one... :-( Good news is that my service becomes recognizable in Poland and I'll be launching it for the rest of the world soon :-) Hope to get some feedback here when that happens.
