Website downtime in many cases can affect user confidence and loyalty to your website. You must keep watching the performance of your website to build trust among the users.
I would like to suggest a free security measure tool to monitor your websites, servers and network failures.
you can monitor up to 2 websites for Free with 15 minutes interval.
-- > checks your website every 15 minutes
--> get trouble alerts by email or sms
--> periodic uptime report
Hope this would do lot of good to all website owners..
