This morning all my test sites have stopped working. They have been working well since Monday. The dns records seem to have resolved ok with wooodsidekennels.com using my ns1.badbison.co.uk my own dns records haven't changed and point to 18.104.22.168. If I type the ip address directly into a browser it displays the default apache page. The only change I've noticed this morning is the mail server has now resolved and delivering all mail. Also there was a warning message on ispconfig advising of an update required. To deal with this from the command line I typed: apt-get update apt-get upgrade and it performed the commands. I then rebooted the server from command line. The warning message is now gone from ispconfig but it's stil not serving the sites up. Can anyone suggest what might have happened? Do I need to restart any services or something? The server was setup using the karmic perfect guide.
