It's important to note that we don't have any proof that this error was actually used by anyone to do anything bad during the short time it happened.
Yes; configuration settings for the web server involving improving performance. Those settings have been changed back to the previous, non-issue ones. So this should not occur at this time, or again.
Is this a mistake that's easy to do for an inexperienced instance admin or just a consequence of too much fiddling and shouldn't be an issue for other instances?
