@olaf Not so unusual to have a single lowly tech responsible for all duties described in TalkTalk job role. I speak from personal experience currently in a very similar role, also in a company that is national critical infrastructure... Not best pleased with my present position, in fact I saw TalkTalk job a couple of weeks ago as I was searching job boards, my present role is so unrealistic I even considered the TalkTalk job for a few seconds.........luckily I smelled another trap
