by Romeo Zwart 08 Dec '15

08 Dec '15

Dear colleagues, The root DNS operators have shared a report about the events observed at the root on 30 November and 1 December. The report is available here: http://root-servers.org/news/events-of-20151130.txt As mentioned earlier on this list, the RIPE NCC will separately also publish a report about our observations at the K-root servers. Please do note that this separate report will also be limited in the level of operational detail that we can share. Kind regards, Romeo

TTM and TTM-based DNSMON visualisations coming to an end
by Romeo Zwart 08 Dec '15

08 Dec '15

Dear colleagues, In July 2014 the RIPE NCC ended its data collection for the Test Traffic Measurement (TTM) project. Visualisations of the TTM data collected until that date, and of the DNSMON data collected via the TTM servers, were kept active for interested parties until now. We plan to stop providing visualisations of the old TTM and DNSMON data as of 1 January 2016. Of course the current DNSMON service (https://dnsmon.ripe.net) based on RIPE Atlas, will not be impacted in any way by this change. Raw data from TTM and TTM-based DNSMON will remain available from the RIPE NCC upon request. We welcome your feedback. Please send any feedback you have to <romeo.zwart(a)ripe.net> directly, or alternatively send your comments to the DNS WG mailing list. Kind regards, Romeo Zwart

finalising the RIPE Documents on DNSMON and ccTLD service
by Jim Reid 07 Dec '15

07 Dec '15

There have been no further comments on the draft documents since the RIPE meeting in Bucharest. We can declare victory and get these published/adopted. Some minor tweaks were suggested when the drafts were originally circulated for comment. Romeo has taken account of these and will incorporate these into the final versions. My thanks to Romeo for his patience and hard work on these documents and to the WG.

K-root DNS Services Incident 1 December 2015
by Romeo Zwart 01 Dec '15

01 Dec '15

Dear colleagues, Between 05:10 and 06:10 UTC today, multiple root operators including K-root received an unusually large amount of query packets. We believe the event was similar to the events that took place yesterday, 30 November 2015. Following our investigation into this, we enabled counter measures shortly before 06:00 UTC. The query load dropped to normal levels at 06:10 UTC. Our post mortem report of yesterday's event will include today's occurrence. Kind regards, Romeo Zwart

K-root DNS Service Incident
by Romeo Zwart 30 Nov '15

30 Nov '15

Dear colleagues, Between about 07:00 and 09:15 UTC today multiple root operators including K-root were receiving an unusually large amount of query packets. This was impacting the overall performance of K-root DNS services, as can be seen for example in DNSMON (with apologies for the unpleasant URL below): https://atlas.ripe.net/dnsmon/group/k-root?dnsmon.session.color_range_pls=0… After initial investigation, the RIPE NCC took counter-measures during the incident. The results of these measures are partially visible in DNSMON. The full effect of the mitigations implemented roughly coincided with the end of the event. We will investigate the events and the effectiveness of our response further and report about this in the near future. Kind regards, Romeo Zwart
