I think the DNS has all updated now, so that’s that: I’m now serving my site through BunnyCDN, which should mean pages, images etc. will load from a server geographically close-ish to each visitor, rather than always from my shared host’s server in the US. The real load time savings will come as more of the site actually gets cached on the CDN servers, of course, so Bunny doesn’t have to fetch so much from the slow shared hosting server.
It might seem like a bit much for a personal homepage, but Bunny is very cheap (the minimum cost of US$1 per month covers up to 100GB of bandwidth, depending on where your visitors live), and the slowness with which my own site loaded here in Australia was really annoying me. So here’s to fast loading speeds!
