We have just released a small update to our monitoring system.
We have previously offered 1,2,5,10 and 15 minute monitoring intervals. Due to customer requests we have added 30 and 60 minute intervals.
We have also added a document size check to our standard http monitor. This checks that the document served by the web site and received by our monitor matches the size you have specified in the control panel. This will not only help detect that your web server is working correctly but can be used in conjunction with our existing content check feature to help detect if your web site is defaced or hijacked.
