One interesting thing I've noticed from this (not sure if this is just my experience or if others noticed as well) but none of the ads seem to be impacted by this. Certainly makes me wonder if those are on a more prioritized and entirely separate infra and SLA that is designed to be more resilient and highly available.
Our local transit system installed video boards showing arrival times for the next trains. It was paid for and operated by an advertising company who in return were able to run ads on their video boards. The functionality for arrival times rarely worked but the displaying of ads never failed. It was obvious where the company's priorities were at.
