Today's #GitHubFail: the endlessly loading issue page.
I'm going to keep tacking things on to this thread as I encounter them. All future posts will use the hashtag if you'd prefer to mute it.
I click the Commits tab on a PR. The blue pjax loading bar starts its slow, erratic crawl across the top of the page. It gets closer and closer to the end, the page remaining unchanged the whole time. It reaches the end. Nothing happens. No errors in the console, no error in the UI, it just didn't work. I click again, there's some requests in the Network tab, but the page remains steadfastly attached to the Conversation view. I press F5, and the commits view finally loads.
