Re: Invalid prefix announcement from AS9035 for 129.77.0.0/16
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.
