RIS data collection outage report
by Erik Romijn 15 Jan '07

15 Jan '07

Subject: RIS data collection outage report Dear Colleagues, Between May 2005 and December 2006, Remote Route Collectors (RRCs) 06, 07, 10, and 14 stored few updates and only partial Routing Information Base (RIB) dumps. These RRCs are connected to NSPIXP2 (Otemachi, JP), Netnod (Stockholm, SE), MIX (Milan, IT), and PAIX (Palo Alto, US). During this period, most update dumps contained no more than a few updates, and many were completely empty, even when many more updates had been seen. Most RIB dumps have been partially stored. Some are empty and some are complete. As the data used by the RIS is read from these files, no RIS tools will have seen these missing routes and updates. The cause for this issue was an error in the permissions set for a tool used by the compression script. This caused the files to be compressed a few seconds after their creation, thus deleting the old file. In most cases, this caused all data written after a few seconds to be discarded. We corrected the error on 2 January 2007. Any data collected on 3 January 2007 or later is stored correctly. We are working to implement better monitoring to ensure that, should this problem reoccur, we will be notified. RRCs other than those connected to NSPIXP2, Netnod, MIX, and PAIX have not been affected in any way. Our apologies for any inconvenience caused. If you have any questions, please e-mail: ris(a)ripe.net Regards, Erik Romijn Information Services department RIPE NCC

RIS to be modified to support 4-byte ASNs
by Erik Romijn 11 Jan '07

11 Jan '07

[Apologies for duplicates] Dear Colleagues, >From 1 January 2007, the RIPE NCC has been assigning 4-byte Autonomous System Numbers (ASNs) to members. To support this, the Routing Information Service (RIS) will soon be modified so that RIS output can include 4-byte ASNs. Any tools you use that parse RIS output should therefore be updated to allow this. Raw data dumps from the RIS will also be affected and you should ensure any tools that read it are capable of handling the new format. The exact date when 4-byte ASNs will start appearing in the RIS is not yet known, as software is being still tested and modified. The RIPE NCC will post a notification three business days in advance of any changes being implemented. Details of the changes to the RIS can be found at: http://www.ripe.net/projects/ris/docs/asn.html If you have any questions, please send an e-mail to ris(a)ripe.net. Regards, Erik Romijn Information Services Department RIPE NCC
