Howdy, We were hijacked aswell, by 27664 16735 Our affected prefixes were: 94.46.0.0/16 194.88.142.0/23 194.11.23.0/24 82.102.0.0/18 195.246.238.0/23 194.107.127.0/24 81.92.192.0/19 193.227.238.0/23 We are trying to contact them in order to get some feedback, and some good explanation for this. In the meanwhile, there are lots of evidence spread around (thanks to RIS RIPE, Routeviews, BGPmon and others) http://www.ris.ripe.net/dashboard/27664 http://www.ris.ripe.net/dashboard/16735 In the meanwhile we are sending notices to the Upstreams of those ASN's, in order for them to apply proper filtering to their downstream customers to avoid situations like this. On the List i was able to found: AS8167 - TELESC AS6762 - SEABONE AS12956 - TELEFONICA AS3549 - GLOBAL CROSSING AS17379 - Interlig I welcome others to do the same, in order to avoid replicas for this situation.

Same problems here, for AS26028 Stefan On Mon, Nov 10, 2008 at 8:54 PM, Mark Tinka <mtinka () globaltransit net>wrote:Hi all. Anyone know how we can contact AS16735 and their upstream AS27664. We think they are hijacking a number of our prefixes (AS24218- and AS17992-originated). Thanks BGPmon: e.g., ==================== Possible Prefix Hijack (Code: 11) 1 number of peer(s) detected this updates for your prefix 61.11.208.0/20: Update details: 2008-11-11 02:24 (UTC) 61.11.208.0/20 Announced by: AS16735 (Companhia de Telecomunicacoes do Brasil Central) Transit AS: 27664 (CTBC MultimÃdia) ASpath: 27664 16735 ===================== RIPE's RIS BGPlay confirms the same, for about the last hour. E-mails to them won't get there (of course), so our NOC are contacting them via Gmail/Yahoo. All help appreciated. Cheers, Mark.
