The peering was cancelled. A disclaimer in advance: this was far before my time here. Part of the explanation is true. If you are present at one of the IXPs where we are, we prefer to configure the peering there. Also, we only configure multi-hop on our exchange-connected RRCs in very rare cases, as it could confuse people. RRC00, which is not connected to any exchange, is the dedicated rrc for multi-hop sessions. > This policy was not, AFAIR, available in any public documents. Part of it was, but perhaps a bit hidden. I'll clarify it and add it in a more obvious place. It was here: http://www.ripe.net/info/faq/projects/ris.html#18 The RIS FAQ says: > Note: Since the database update capacity is currently limited, we do > not accept any new peers on RRC00.

Would anyone? The view of RIS is always limited by the amount of data we can process and the locations where we are present. Therefore, we would be very happy to hear ideas about how to improve the usefulness of the data we collect. Should we get more full feeds at exchanges (requiring bigger hardware)? Or more locations? Which locations? Or accept more multi-hop? regards, -- Erik Romijn RIPE NCC jr. software engineer http://www.ripe.net/ Information Services dept.
