Intrigued by the fact that many Bibliogram/Nitter/Invidious/Piped instances are from sites that also offer other services, I set out with good will to sift through them one by one, and here are the results: (and I must say I discovered many instances that are not indexed on the “official” directories).
Obviously if I missed any I will point them out and add them.
I’ve never experienced any of these, so I’m assuming they have been fixed
Nonetheless, many instances in my research aren’t listed in the source you linked 🤔

This list is made by scraping the official list of instances for each project, so any instances not on the official lists will not be here.
