I received a phas notification about this today as well...

I couldn't find any relevant data confirming the announcement of one
of my /19 blocks, until a few minutes ago when i checked the route
views bgplay (ripe bgplay turns up nothing) and can now see 8997
announcing and quickly withdrawing my prefix
