| A website requires a functioning network, DNS and other background Internet services to operate correctly. | It is also requires that the website application responds in an appropriate amount of time. Poor performance is the main reason for website abandonment. | Finally, a new or returning customer has reached your site expecting information or a list of products. Is the site displaying the information? | ||
A comprehensive website monitoring and alerting solution for your company makes sure that these three components are checked in detail. |

Please find below the complete list of Error Conditions we have found to be common after over five years of monitoring. There are several hundreds of different error codes made available by different vendors and software consortiums such as the World Wide Web Consortium. The published standards for HTTP 1.1, for example, contain many errors, but only a small handful are actually reported by protocol compliant web servers. |
