There is frequent forum discussion of online courses. Online elements are now embedded in many brick-and-mortar classes.

A downside is system outage and downtime, both scheduled and unplanned. For example:
- Pearson had a planned outage from 8pm ET Saturday June 24, 2017 until noon ET Sunday June 25, 2017. (16 hours)
- This quickly became an unplanned outage with system downtime estimated at an additional 2 hours, until 2pm ET Sunday June 25, 2017.
- The outage is now extended indefinitely, and has lasted over 24 hours. sick

Additionally, downloaded Pearson textbooks are found to be inaccessible, as the Pearson software performs authentication when there is an attempt to access the downloaded materials. With the Pearson servers down, authentication fails. frown

These problems simply don't exist with books. smile
