One drawback of using multiple companies for web hosting is that if one of those companies ceases to offer services, it can cause malfunctions on other sites which rely on files to be found on the site operated by the company which no longer offers services. That's the case with regard to graphic files of mine (and perhaps other files, too) which were hosted earlier by Yahoo! Geocities.
It isn't as if it caught me completely unaware; I'd known for some time that Yahoo! was closing down all of the free Geocities hosting accounts. But I'd hoped that they would at least continue to hold onto the files they already had, so that links I'd created in numerous places on this blog (and elsewhere) wouldn't become obsolete. Not so. Hence, if you're going through earlier blog posts on this blog site and you find missing images and other files, that's the likely explanation.
This blog post is an example of what I'm talking about. The text is still there, but the images previously displayed in the blog post are now gone! It's really annoying.
Fortunately, I do have those files elsewhere (on CD-R discs), since I've always made a habit of never uploading any files to a web hosting program without also backing up the files on CD-R discs or other media. Unfortunately, going through all my blog posts here and fixing things (by finding those files, then uploading them to a new host, and then changing the links so that they point to those new file locations) will be a very time-consuming proposition, and a potentially frustrating one, on account of the huge number of files I've burned onto various CD-R discs of mine. At present, my computer time is very limited, and it's much more important for me to address my economic situation by getting a job very soon; so fixing all of those links so that they work properly again is not one of my highest priorities.
