Pingdom is one of my favourite free tools for monitoring uptime of the websites we create – everyone should use it! It not only saves money but, crucially, it avoids embarrassment with clients and customers. How?
It comes down to understandng how reliable your site is. Downtime can be very damaging – it can lead to loss of sales, upset customers and creates a negative image. If people can't access your site, the chances are they'll head elsewhere.
