Not much more progress
I regret I still cannot contact any of our websites by HTTP. They either give 'connection refused' and time out. Those that give connection refused I can contact by FTP. email I think is working on those that I can contact by FTP but not on the others.
I have successfully got through to our account manager and requested that the apache http module is restarted. He has sent this to the engineers but if they have done it there is no result yet.
