The Carsurvey.org web server is still stuck in support hell. I’m pretty sure it’s a hardware fault, but no one at the hosting company (The Planet) seems to have got to the source of the problem. In the medium term, I’m definitely going to move hosts, as my recent experiences support at The Planet have been very poor.
Sorry for the long wait, and if things aren’t resolved soon, I’ll just rent a server from someone else, and rebuild Carsurvey.org from my backups. That would take a day or so, plus the time needed for the DNS change to take effect, so I’m still going to give The Planet one last chance to fix the problem.
