Watch Dog

Watch Dog is a free service provided by us that periodically checks your Web and Email server to see if they are responding.

How does it work

  • Our servers ping your server every 15 minutes
  • If any of your server does not respond, retry attempt are made for the next 5 minutes - one attempt per minute.
  • If these attempts fail our system generates an email notifying you about the problem. This notification email can be sent to a mobile phone or a pager.
  • Every week you will get a report via email with a summary of all pings to your server(s)


Since the incremental cost of adding your server to this service is almost negligible, we can offer it for free. Bottom line - we don't have to pay anyone, we don't charge you either.


Our servers will ping your server every 15 minutes. This interval cannot be changed (at least for the time being).
