My difficulty instituting a CDN continues
I had been using a CDN, the acronym for “Content Delivery Network”, to deliver the pictures on this blog to your browser. The reason for doing this is to speed up the load time of the web page and it certainly fit in my “Experiments with WWW” or whatever I’m calling it. A CDN stores your pictures/videos/whatever (content that is larger than the rest of the html in a site) and when the page loads your server doesn’t have to spend a bunch of time pushing that heavy content around, it can focus on the simpler and faster html and associated scripts.
But, what happens when your CDN provider gets shut down and you didn’t even notice? Or get a notification? And what if that happens at exactly the same time that you upgrade your caching plugin, which leaves a file on your server that breaks the website? And not just your website, but the other three websites on the same host? What happens is that even if you put your server right side up again, all of the pictures that you call on the deceased CDN no longer answer.
Oh MY GOD this is SO boring!
The CDN I was using was called “SimpleCDN“. As I recall, they offerered 150Mb of storage, and up to a Gb download per month for $FREE. I’m using MAYBE 10% of that. I could pay some “cloud” service like Amazon $100.00/mo. And there are others, most of which are as expensive. SimpleCDN “fit my needs”, as they say. Apparently, SimpleCDN were using a hosting service then reselling it as a content delivery network. This article explains it better than I will, so you should read it if this type of thing is interesting to you. So the host shut them down. Hit the kill switch, with no advance notice. UH OH! Now you have subscribers who are using your service to run their websites, and they all go dark (sort of, I mean, their content wouldn’t be visible if the page tries to refer to stuff on the CDN server).
Two lessons I learned from this experiment:
- You get what you pay for. This is an immutable natural law. Whether it be for Graphic Design, a CDN, or a bottle of wine.
- If you want your blog to stay online, you MUST do some maintenance and pay attention to all the stuff you have tacked on to it.
