Anyone here who is on the Vienna/London/Amsterdam exchange(s) and who is seeing what is alleged here: above.net leaking and/or flapping routes that are not their own ? Is there a lookingglass at any of these exchanges that is publicly accessible? bye,Kai

Hmm, please give me a list of the routes advertised as well as the peering points this was or is seen at.
Vienna Internet Exchange.
London Internet Exchange.
Amsterdam Internet Exchange.
Routes are 202.36.147/24, 202.36.148/24 and 202.50.71/24 ie superblocks of the same.
Any exchange that is more than a backroom operation in someone's closet has a policy prohibiting such unauthorized announcements. I will assume for now that these are route leaks that are escaping through above.net's BGP distribution filters: something that is entirely within the real of possibility, but which has to be stopped.
My suppliers refuse to stop advertising the /16s containing my netblocks into above.net - but claim to have set up /24 adverts into their other suppliers.
Unfortunately, those /24 adverts appear to be flapping. <sarcasm>I wonder who could be causing that and why they'd do it? </sarcasm>
