Hi Josh,
Thank you for your reply.
24 Students in a computer lab are instructed to work through the Data Visualization Basics Primer https://rstudio.cloud/learn/primers/1.1
Students are not logged in to rstudio cloud, just working through the primer on the website. After a 5 or so minutes of working through the Primer, the site hung up for 5-10 students (seemingly) simultaneously. They could hit the reload, and it would restart, but then it would continue to hang up for handful of students. I would guess this was happening they were working on the "A code template" or the "Aesthetic mapping" pages. I'm going to be teaching another lab this afternoon and we'll try it again, so I will try to keep better track of where the issue is occurring (there is another lab being taught right now, although there are fewer students in that section ~12, but it is taught by a different instructor).
Thanks again for you help,
Jeremy
