Why are some of my questions not being posted on the website (technical failure?)

In the past month or so I’ve “posted” questions, but after a few hours I’ve gone back to fluther to view them and they aren’t there. I know I’ve finished posting them, however I don’t always go back to the home page to check.

Also, I haven’t received any notifications about Mods temporarily taking them down. Is this a technical complaint you guys have been hearing lately?
