I should start by saying that the server on which this blog is posted was set up in June 1993. Although the physical object has been replaced a few times, and had been “virtualised” about 15 years ago, a small number of the underlying software base components may well date way back, perhaps even to 1993. This system had begun to get unreliable in recent years, and it was decided about 6 months ago to build an entirely new virtual server and then migrate stuff to it.
