RIS data collection outage report

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.
