I can no longer access my nildram mail via this address: https://netmail.pipex.net. Is this due to migration to the new TalkTalk mail system or is something else broken? Any attempt to load that address gives 'netmail.pipex.net unexpectedly closed the connection'.
There is a Service Status message (Email) indicating that there is an issue with the pipex webmail sign in and that the engineering / email teams are aware and are working on a fix.
You're very welcome to stay and keep an eye on the Service Status message but for ongoing support you'll need to contact TalkTalk Business.
