13 Shane Kerr. RIPE 45, May 2003, Barcelona. 13 Database Operations Smooth sailing –average response time is well below 1 second –load approximately 70% higher than last year New ARIN mirroring scheme next week –Use difference to generate NRTM, rather than full load –No down-time, includes allocations and assignments Tertiary (i.e. off-site) server in planning phases –Withstand catastrophic, city-wide failures –Manual failover by updating DNS for whois.ripe.net –Part of larger project to increase critical service reliability

15 Shane Kerr. RIPE 45, May 2003, Barcelona. 15 Unreferenced Person Cleanup Protect privacy of users –Person objects remain undeleted when contacts change Person objects unreferenced for 90 will be deleted –A modify of the object “resets” the counter sent after 60 days –Limit to 2000/day to avoid overwhelming users & server Deletions begin 29 May 2003

16 Shane Kerr. RIPE 45, May 2003, Barcelona. 16 IPv6 query proxy status Operational issues resolved –Solaris patches and move to Sun box –DNS update hid AAAA record for 10 days –Moving to standard monitoring and failover Source code public release made 90% of queries come from only 7 IP addresses Still see more 6bone than RIR addresses
