Our hosting provider reached out to me about an hour ago to alert me/us that the machine currently hosting this site (and others) has developed a fault and they need to migrate everything over to a new device. This very well may already be completed at this stage, as we're considered a "low power" site that wouldn't take long for their systems to move. In the event you notice any site weirdness, this is likely to blame.
I'll have an update posted when I know more. Many thanks all for your patience!
