I'd guess the shift from Desktop to SaaS, the demands of keeping a service running 24/7 are quite high compared to just offering a download.

I was delivering reliable SaaS applications in 1999, and by that time I was already behind the pioneers by 5+ years. So that's not anything new, and on balance I don't think the demands are any higher. Some things have become harder, others easier.
