There are five main symptoms of problems with the availability and functioning of a website:nn1. Connection timeoutnIt's usually caused by:na) network failurenb) server hardware failurenc) server software failure.nAll the above can also be results of an overload - when web traffic exceeds the infrastructure capacity.nOur system reports a timeout when the three monitoring stations are unable to establish a connection to a website for more than 5 seconds.nn2. HTTP errornUsually resulting from an incorrect server or website configuration.nMost common http errors:n - 301 Moved permanently (redirects themselves are not errors—unless there are too many)n - 302 Moved temporarily (as above)n - 400 Bad Request (the request cannot be fulfilled due to bad syntax)n - 401 Unauthorised (authentication failed)n - 403 Forbidden (usually when file or folder rights are set improperly)n - 404 Not Found (missing file or a folder)n - 500 Internal Server Error (a generic error message, given when no more specific message is suitable)n - 502 Bad Gateway (the server was acting as a gateway or proxy and received an invalid response from the upstream server)n - 503 Service Unavailable (usually the first stage of an overload, the second stage is connection timeout) nnOur service recognizes and records all http error messages.nn3. Wrong or missing page contentnIt can be a result of:na) database errornb) website functional errornc) human mistake.nOur services can be configured to search for a specified text string on the monitored page.nn4. Website malfunctionnOur system is able to test both simple forms (e.g. contact, search, login) and entire processes—e.g. purchasing.nn5. Website loading time is too longnWebsite slowdown could mean problems on different levels: server, internet connection, website structure or its content.nnOthernSuper Monitoring also detects other problems:n - the upcoming expiration of the internet domainn - the upcoming expiration of the SSL certificate or its invalidityn - presence on blacklistsn - search engine robots being blocked.
