A perl wrapper script is used to extract the data from file and run the test, update the datafile and if requested, email people. A separate CGI script produces the HTML output of the list of broken hosts.
n xxxxxxxxx (xxx.xxx.xxx.xxx) [open] x.xxx ms x.xxx ms x.xxx msfrom tcptraceroute when the -E switch is enabled. We run a control test without the -E switch, and will only list the site if it works without but not with it. We can make no guarantees that the data are correct, accept that the test is not perfect (although we do perform a control test either side of the ECN test, network outages may result in us incorrectly identifying a problem), and the data are provided on a 'best efforts' basis. We do now lookup the IP at the start, and use only that (to prevent us recording inconsistent data due to round-robin DNS).
Each host will be retested once every six weeks.
The contents of the "Organisation" field is provided by the submitter, and we can take no responsibility for it.
