4Today the network 18.0.0.0/8 disappeared from the Internet, it is now reachable.   I went to different looking glass (MAE East, LINX, GRnet) and 18.0.0.0/8 was not in their routing table.   Is it related to a major problem?

Yes. Not enough people understand RFC1918.

Including me, apparently, since RFC1918 makes no mention of 18/8. And including MIT, probably, since that's their /8. Unless somebody between MIT and the outside world screwed up something involving RFC1918, and you're just being cryptic?
