Thanks to a very my very unfortunate mistake my former hosting provider, TekTonic.net, deleted the Virtual Server that stored this website (and a bunch of other things). Long story short is that I didn’t have sufficient backups of the website content and at this stage it doesn’t look like it will be possible to restore the server as it existed before.
I will try to restore as much content as I can recover to this website over the next couple of weeks, unfortunately it’s very likely that some things will have been lost forever.
For more details on exactly what happened see my post here: TekTonic Deleted My VPS
You should take this as a timely reminder to ensure you have useful backups of things that are important to you, even if you believe them to be safe.
