Lots of people were affected, but none significantly. They originated 86,747 networks very briefly (less than a minute at 7:23 UTC), and I don't think anyone outside Telecom Italia's customer cone even saw them. So the impact was really, really limited. The correct origins were being reasserted even before the last of the announcements came over the wire. It always irks me when I see "routing alerts" that arrive hours after the event is over, without any of the context that would allow you to know whether it had any real impact. Your instinct to check looking glasses is the right one, but you have to move quickly and know where to look. Of course, I'm biased. --jim On Fri, Oct 9, 2009 at 9:20 AM, Adam Kennedy <akennedy@cyberlinktech.com>wrote:
Agreed. Our prefixes at AS40060 were announced as well. I received a notification around 7:00am EDT that our prefixes were detected announced from AS9035 with the same upstream AS1267.

Hi Matthew, You are not the only one having this issue. They are announcing some other prefixes as well!

About 4 hours ago BGPmon picked up a rogue announcement of 129.77.0.0 from AS9035 (ASN-WIND Wind Telecomunicazioni spa) with an upstream of AS1267 (ASN-INFOSTRADA Infostrada S.p.A.). I don't see it now on any looking glass sites. Hopefully this was just a typo that was quickly corrected. I would appreciate if people have time and can double check let me know if any announcements are active except from our AS6128/AS6395 upstreams.
If this were to persist, what would be the best course of action to resolve it, especially given that the AS was within RIPE.
