Question
Wonder if anyone can recommend a service. I don't need anything fancy. Maybe once an hour a check to make sure my website is up.
Answer
Try using InternetSeer.
It has worked well for us.
If you use any such service, be careful to provide them with an email address for yourself that is not also reliant on the same hosting service that houses your website. Otherwise, when your site is down, so is your email & you get no notice.
Answer
Thanks - I will check into them.
