In search of 404

I am trying to detect 404 when saving / publishing habratopik :)



And at the same time I warn you that tonight, from about 2-3 o'clock at night MSK Habrahabr will be unavailable due to the next UFO visit with some technical work that we plan to spend on the server where Habr is spinning. I hope we can do it in an hour or two;)



UPDATE as soon as it did not save and did not publish - and with all the daws, and in the personal blog, and in the collective - 404 did not find. wtf?

UPDATE-2 UFO visit behind, everything seems to be ok? ;)
