My first blog post that disappeared. The void is coming.

Hello good people,

I have no idea if I'm the first one that experienced this. I actually wrote quite a long blog post this moring. I wrote it in the browser, submitted it and it was shown on my blog side. Then a few seconds later it disappeared without a trace.

I refreshed my blog site a few times.. Checked whether it is still in the cache... it wasn't and all methods failed.

Am I the first one that experienced this? Did I do smth wrong? Does this happen from time to time or was this a rare event?
If you have any idea, feel free to post.
