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 tech list.
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.
According to Henk Steenman (CTO AMS-IX) everything is back to normal operations. AMS-IX is still investigating what happened.
I wouldn't call having to disable one link in the ring between the four locations because spanning tree wouldn't converge otherwise "back to normal", but yes, the AMS-IX is back to working order, as the large number of backlogged "we are experiencing an outage" messages on the AMS-IX mailinglist that just came in indicate... It's very interesting to see the traffic stats at http://www.ams-ix.net/hugegraph.html Usually, incoming and outgoing traffic is the same. But during this problem, much more traffic went out than came in. Iljitsch van Beijnum
