Well. That was a bit longer than expected. I’ve finally retrieved the slime-covered remnants of my blog, attached bolts to its neck and re-animated it with lightning.
For something that I took down for “a few weeks” while I changed hosting providers, it ended up lying pretty much dead in a ditch for nearly 3 years. All it took was for me to take a week off work between jobs, and finally get around to dusting off the WordPress database backup, and working out how to ram it onto an EC2 instance, which then involved a lot of time with setting up an Amazon RDS database instance, and working out how to connect the bits (which was surprisingly fiddly).
