Atlas F.ROOT ping
by Peter Gervai 09 Jan '14

09 Jan '14

Hello, Atlas helped me today first to see a hard-to-detect bug: F-root anycast algo works fine for v4 but fails miserably for v6, as instead of AMSterdam it sends all traffic to some remote island in the pacific. ;-) Seems to be the reverse true for M-root: ipv4 sends me off to nowhere land while v6 is great. A-root follows the F-suit. (C-root is not a good avertisement valie for Cogent, with v4 only address and considerable ongoing pkt loss.) Thanks! Peter

2 probes down
by Jan Hugo Prins 23 Jan '13

23 Jan '13

Hello, This morning I got a notification that the probe in my datacentre is down. I checked everything and he looks just fine and is happily doing traffic. Then I noticed that the one behind my home fiber connection is also down, and that the starttime is about the same. Both of them at 6:56 this morning. Also checked that one and he is also doing traffic just fine. Houston, do we hava a problem? -- Met vriendelijke groet / Best regards, Jan Hugo Prins Infra and Isilon storage consultant E: jprins(a)betterbe.com T: +31-53-4800694 M: +31-6-26358951 S: jhaprins W: www.betterbe.com <http:///www.betterbe.com>

Parametrization of UDM requests?
by Stephane Bortzmeyer 15 Jan '13

15 Jan '13

It seems that the parameters used for an UDM are the same for all probes. For instance, I would like to do a DNS UDM with a different question for each probe, something like "%p.mydomain.example" where %p would be replaced by the Probe ID. Is it possible? Or do you think it would be a worthwile improvment?

I think Olaf did not refer to the UI of the UDMs, but to the UI of the probes. At least for me as well, the graphs of the statistics started to show no data for a period starting sometime between Jan 5 and Jan 6, 2013. At some point, I got the message that there was some maintenance going on on the Atlas infrastructure side. However, nothing changed with respect to the graphs not showing current data once the maintenance was through. Interestingly, the graphs started showing something again for data collected starting as of about 8 AM UTC this morning. Apart from some interruptions due to my public IP address changing, my probe was considered "up" all the time, and I also saw it running its tests and getting responses to the various probe messages. However I still need to figure out (I am sure it is in the documentation, I just didn't get around to looking for the relevant parts yet) how to access the raw data for recent measurements to see whether that data not being displayed in the graphs was due to the collected data somehow not getting to the Atlas infrastructure for some reason (despite probe being considered up), or whether there was just an issue displaying the collected data. Has anyone else seen similar issues and/or some idea what might have happened? Thanks! Kind regards, Joachim

[UDM] Cannot select "recursion desired" for DNS
by Stephane Bortzmeyer 08 Jan '13

08 Jan '13

When creating a new UDM with DNS (or DNS6), the checkbox "Recursion desired" is greyed and un-selectable. I know that recursion can request more resources from the DNS servers. Is it why it is currently unavailable? It does not seem documented in <https://atlas.ripe.net/doc/udm> which just says: Recursion desired Enable recursion. This is the RD flag described in RFC1035.

The graphics for the pings seem to have vanished in the UI. At least for my account...
