<p class=MsoNormal>As you may be aware from recent news reports, traffic to the
youtube.com website was 'hijacked' on a global scale on Sunday, 24 February
2008. The incident was a result of the unauthorised announcement of the prefix
208.65.153.0/24 and caused the popular video sharing website to become
unreachable from most, if not all, of the Internet.<o:p></o:p></p>

<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>The RIPE NCC conducted an analysis into how this incident
was seen and tracked by the RIPE NCC's Routing Information Service (RIS) and
has published a case study at:<o:p></o:p></p>

<p class=MsoNormal>The RIPE NCC RIS is a service that collects Border Gateway
Protocol (BGP) routing information from roughly 600 peers at 16 Internet
Exchange Points (IXPs) across the world. Data is stored in near real-time and
can be instantly queried by anyone to provide multiple views of routing
activity for any point in time.<o:p></o:p></p>

<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>The RIS forms part of the RIPE NCC's suite of Information
Services, which together provide a deeper insight into the workings of the
Internet. The RIPE NCC is a neutral and impartial organisation, and commercial
interests therefore do not influence the data collected.<o:p></o:p></p>

<div>
<p class=MsoNormal>The RIPE NCC Information Services suite also includes the
Test Traffic Measurement (TTM) service, the DNS Monitoring (DNSMON) service and
Hostcount. All of these services are available to anyone, and most of them are
offered free of charge.<o:p></o:p></p>
