When I was a university researcher, after publishing my first paper in the role I carefully read the policy requiring making data available, as I wanted to be correct by the book, but also have my data (which I took pride in) publicly available for critical review. The process as described was simple, though I soon found there was no mechanism implemented to actually achieve this. URLs and systems no longer existed, no alternatives available. I requested to publish via an external provider and was informed I would be fired if I did so. Disappointing to say the least.
