Ripe tested a new attribute that crashed the internet, is that true?If it in fact "crashed the internet", as opposed to "gave a few buggy routers here and there indigestion", you wouldn't be posting to NANOG looking for confirmation. :)https://www.ams-ix.net/statistics/ Not whole internet, but a part. And the "few buggy routers here and there" were mostly Cisco CRS-1's which didn't understand the new attribute and sent a malformed message to all peers, causing them to close the BGP session.
In a way it remind me of the ASN4 bug .. Until a vendor fix is available I guess that the details are better left off public mailing lists. http://www.uknof.org.uk/uknof12/Davidson-4_byte_asn.pdf
I think most of the impact was limited to Europe, especially Amsterdam area.
Yes, It had an effect on ISPs which are connected to RIS. http://www.ripe.net/ris/ AFAIK this mean ASes at LINX and AMS-IX . The LINX graph shows a similar (but smaller) dip of 50-60 GB. Thomas
