You can’t always depend on third party services.
A few years ago I had one of the busiest weeks I’d had in a long time, and I wasn’t able to monitor my queue of scheduled blog posts. For weeks I had been scheduling blog posts on Medium, and they had been working just fine. It didn’t occur to me that they would suddenly stop working.
So during my super-busy week I needed my scheduled blog posts to run as normal, posting on my behalf, daily each morning, as always.
But oh, things didn’t work out. As soon as I stopped looking, Medium quit posting my scheduled stories. So my goal of posting a story every day for a year suddenly ended because of undependable technology.
Anyway, the lesson here is that you can’t trust third party systems. They will fail at surprising and unexpected times. Don’t put your faith into them. Always be on the defense. Monitor your systems. Build in redundancy. Check things manually from time to time. You never know when the systems may stop working.
