The requests were completed successfully, though, in every case we experienced. It was just the response that wasn't successfully getting back to the user for some reason.
Has anybody noticed this behavior recently? We're trying to determine if this is still a problem or not. Also, if you have experienced this behavior and would like to help out, please comment here with any information that you think might be relevant--browser, operating system, actions you were taking when you experienced this, etc.
Thanks!
