Request to test TCP and UDP to the root servers separately.
by Leo Bicknell 23 Mar '12

23 Mar '12

My day job has had some interesting discussions lately about TCP to the root servers based on a few odd behaviors we've had reported to us over the past few years. There aren't any surprises in this data, it's been known for a long time some people think DNS is UDP only for instance, some firewalls are broken, and so on. What we realized though is that there is no wide-spread measurement of how often TCP is a problem. Immediately my thought went to the Atlas probe network. It's distributed enough it could give an interesting indication of how often TCP DNS fails compared to UDP DNS. Perhaps the rates are so similar it's a non-issue, perhaps TCP fails much more often. Would it be of interest to the Atlas community to have the probes try and query "." via both UDP and TDP from each of the 13 root servers (perhaps v4 and v6 separately), report back that data, and then generate a report on the results? I would be happy to assist in preparing or presenting a report on the results! -- Leo Bicknell - bicknell(a)ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/

Small changes deployed on this Wednesday
by Robert Kisteleki 16 Mar '12

16 Mar '12

Dear Atlas Users, On Wednesday we've deployed some changes to the UI. The most notable change is that from now on the download format of your probe's measurement data is JSON. The actual syntax is pretty much self-explanatory. The DNS anycast map now visualises server versions and SOA serials too. We made further changes to the way we show static network configuration of a probe on the "probe status" page. We also did some preparations to include Atlas in RIPE NCC Access, the RIPE NCC Single Sign On system. Regards, Robert, for the RIPE Atlas team

ghostgraz.com
by Simon Josefsson 14 Mar '12

I was debugging my local DNS resolver when I noticed peculiar lookups from the Atlas probe for 'ghostgraz.com'. It seems to happen once in a while. Does anyone have any idea what this is? I don't see it in the list of built-in measurements, and I don't recall configuring anything related to that site myself. /Simon 14-Mar-2012 08:55:36.732 client 192.168.1.48#58740: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 08:55:36.734 client 192.168.1.48#40389: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 08:55:36.737 client 192.168.1.48#44142: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 08:55:36.740 client 192.168.1.48#59254: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 08:55:36.742 client 192.168.1.48#56991: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 08:55:36.745 client 192.168.1.48#59319: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 08:55:36.769 client 192.168.1.48#55435: query: ghostgraz.com IN A + (192.168.1.47) 14-Mar-2012 08:55:56.001 client 192.168.1.48#49742: query: caldwell.atlas.ripe.net IN AAAA + (192.168.1.47) 14-Mar-2012 08:55:56.146 client 192.168.1.48#34211: query: caldwell.atlas.ripe.net IN A + (192.168.1.47) 14-Mar-2012 08:58:38.199 client 192.168.1.48#42327: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 08:58:38.202 client 192.168.1.48#53097: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 08:58:38.204 client 192.168.1.48#54101: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 08:58:38.207 client 192.168.1.48#52439: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 08:58:38.210 client 192.168.1.48#37104: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 08:58:38.212 client 192.168.1.48#59275: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 08:58:38.216 client 192.168.1.48#49299: query: ghostgraz.com IN A + (192.168.1.47) 14-Mar-2012 09:01:28.778 client 192.168.1.48#58887: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 09:01:28.781 client 192.168.1.48#52689: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 09:01:28.784 client 192.168.1.48#40593: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 09:01:28.787 client 192.168.1.48#51568: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 09:01:28.790 client 192.168.1.48#36493: query: ghostgraz.com IN AAAA + (192.168.1.47) 14-Mar-2012 09:01:28.792 client 192.168.1.48#33057: query: ghostgraz.com.lan IN AAAA + (192.168.1.47) 14-Mar-2012 09:01:28.796 client 192.168.1.48#49588: query: ghostgraz.com IN A + (192.168.1.47) 14-Mar-2012 09:01:34.977 client 192.168.1.48#35392: query: www.ripe.net IN A + (192.168.1.47)

probe 466 running unattended
by Wilfried Woeber, UniVie/ACOnet 05 Mar '12

05 Mar '12

Dear Atlas-Team! I am almost on my way to Costa Rica for the next ICANN meeting, and taking some time off before, and - more extensively :-) - after. Thus my probe at home, #466, may go offline if there's an environmental or ISP-upstream problem, that prevents its automatic recovery. I am scheduled to be back home around the Easter weekend, probably on Sunday, April 8th. Also, the probe in my office, #414, runs unattended during that period, but you are welcome to contact <noc(a)aco.net> for hands and eyes to get it back up, just in case. Best regards, Wilfried.

OT(?) SamKnows/EC Test Project
by Wilfried Woeber, UniVie/ACOnet 21 Feb '12

21 Feb '12

Maybe this is a tad off-topic, but maybe not... Has anyone been able to get in touch with a human being (over eMail) regarding the participation in their measurement project? Any and all of my attempts till now failed miserably, they just keep sending me reminders to accept their fine print; and I am just about to pull out/unsubscribe. Any input or advice gratefully accepted. Best regards, Wilfried.

Protocol/Technology testing?
by Daniel AJ Sokolov 15 Feb '12

15 Feb '12

Hello, Are there any plans to extend the Atlas probe's functionality from simple Pings to more sophisticated testing? For example: Can actual payloads be transferred (http, ftp, SMTP, NNTP etc.) and with which parameters? Is encryption available (https, ssh, starttls, etc.)? Some countries and/or ISPs restrict what users can do. Currently, Iran is inhibiting all encrypted international connection. For the users on the ground this is horrible - no gmail, no yahoo, no online banking, no Tor network - no proivacy! Yet on the Atlas network everything seems to be fine, as pings still work. (However, only one of the six probes is online, the rest has been offline for weeks. And the one that is online was offline for weeks until a few days ago. I'm not sure what the issue is there.) It would be good to know if some protocols are not available in a certain jurisdiction. Of course, such tests could be done at a much lower rate than Pings - some maybe every hour, others every couple of hours. Then again, the probes might not be mighty enough?
