Website Monitoring

We monitor websites regularly - to check if the sites are UP or DOWN. We also check website performance (response time). Our website monitor will check any URL - http or https.

We've got what you need!

Internal site monitoring (over a local connection) can never provide a complete end-to-end test. We provide the independent website monitoring service you need. Our monitor site service is a valuable tool for Webmasters and anyone else who wants to monitor a Web service - whether hosted internally or by an ISP. We also license our system to people interested in running their own independent monitoring service.

Our Service

Our Service


We email you when your site goes DOWN - using regular email or SMS (Short Message Service) text messages to your pager, mobile phone or cell phone.


We monitor your site regularly with options of from every 30 minutes up to every 5 minutes.


We give you confidential online reports of your website performance (uptime, downtime, response time) summarised by month with breakdowns by day.


We give outstanding support to all our users. We explain in detail any HTTP errors for your website. We examine patterns of DOWN time to help identify sources of website problems.


Please look at our sample accounts below to see the type of statistics you get. If you have several URLs to monitor, we give you your own check group to make access to your accounts easier. Please look at our sample group D1.
