I couldn't find anything on this one, so maybe someone has a good idea on what would be considered good practice in a scholarly context.
For a semester project, I have to observe an online newspaper and summarize their weekly topics. Each week I have to submit a short note containing my findings and analysis, and of course quote the source properly according to the Chicago style.
However, the website was down for a day or so and I would like to have that documented. But how to document and cite absence?
