"This table is generated from objects in the RIPE and RA databases. If there is something missing or wrong then please refer to the original data in the databases.
The information given here can apply to peering arrangements between members anywhere in the world, and is not limited to the traffic flowing through the LINX."
When the peering matrix perl script was written (false modesty be damned :), we decided that it was too complicated to bother with anything other than the public information in the RA/RIPE db's. The other though was that if two AS's peer someone else and not at the LINX, then that is their loss, and not one that we should have tried too hard to fix for them. The use of the RA/RIPE db's was seen as the only "neutral" data available, and neutrality was (and I think still is) a priority at the LINX. Peter
