There seem to be large scale problems at the AMS-IX. BGP sessions with
peers keep oscillating. Since their own addresses keep jumping all
over the place, it is not possible to reach anyone over the AMS-IX
I have disabled all AMS-IX peerings for the networks I manage, and I
suggest everyone who is present there looks in to doing the same.
