IP => Location on the planet
by Laurence F. Sheldon, Jr. 31 Oct '15

No follow up required or expected. FYI geo-location fans. While sitting on a toilet in a hotel in Kansas City, Missouri, US of A, I chanced to log-on to Facebook from my Kindle, and the lap-top in the on the desk in another room, Facebook alerted that I had logged on from Caracas, Venezuela. I have not checked--we might be in the same time-zone.

Microsoft Geo-IP Admin needed
by Fredy Kuenzler 30 Oct '15

30 Oct '15

Can anyone point me to a Microsoft Geo-IP admin? Their Geo-IP for live.com/outlook.com seems to be rather outdated. We get complaints for 85.195.208.0/20 and 85.195.224.0/19, pointing to Antarctic instead of Switzerland. Any commercial Geo-IP shows correct information, but Office product activation fails. Twitter thread: https://twitter.com/fiber7_ch/status/630880605971025920 Offlist response is fine. Thanks. -- Fredy Kuenzler --------------------- Fiber7.

Satellites and submarine cables
by Sean Donelan 30 Oct '15

30 Oct '15

Since the weekend's list problems seem to have died down. How about some infrastructure news. http://spacenews.com/from-russia-some-unofficial-assurance-about-lurking-lu… >From Russia, Unofficial Assurance about Intent of Lurking Luch Satellite http://www.nytimes.com/2015/10/26/world/europe/russian-presence-near-unders… Russian Ships Near Data Cables Are Too Close for U.S. Comfort This seems to be a case of "I know you can see me, and I can see you." Its not new. Multiple countries have demostrated submarine and satellite capabilities over the decades ... more submarines than satellites. But generally everyone has more to lose than gain. What is different is the increasingly public rhetoric. Occasional satellites or submarine cable disruptions haven't had long term impact on the US mainland due to US connectivity options. Carriers serving the US mainland regularly have outages and repair submarine cable and satellite problems. But countries with less connectivity options could get pushed around more, along the lines of "Make him an offer he can't refuse." Some of the public rhetoric may be for allies.

Level 3 issues in Chicago
by Randy Carpenter 30 Oct '15

30 Oct '15

A network that we manage is having trouble getting to several sites. The common point of failure appears to be Level 3 in Chicago. Connections work fine from our direct upstream, so it appears that Level 3 is not allowing traffic sourced from the net block in question. Can someone from Level 3 ping me off list? thanks, -Randy

NANOG list attack
by Larry Blunk 29 Oct '15

29 Oct '15

All, Just wanted to apologize for the attack over the weekend. The posts came from a email address that was subscribed to the list, so it was not subjected to moderation. While a filter was added to block further posts (which were made in a short time window), there were existing message queues that were not cleared in a timely basis. As Job Snijders (a fellow Communications Committee member) noted in an earlier post, we will be implementing some additional protection mechanisms to prevent this style of incident from happening again. We will be more aggressively moderating posts from addresses who have not posted recently, in addition to other filtering mechanisms. Regards, Larry Blunk NANOG Communications Committee Admins(a)nanog.org

configuration sanity check
by marcel.duregards＠yahoo.fr 29 Oct '15

29 Oct '15

Hi Nanogers, Any recommendation about a software which check the live config of cisco/juniper devices against some templates ? The goal is to have a template about different function device, like: - CORE device must have this bloc and this clock - PE device must have at least that and that - CPE must have this and that - Distrib switch block 1 and block2 - etc... And the software run once every day to check which device do not comply with those rules and generate an alert. Thank, - Marcel

29 Oct '15

Could a CenturyLink network admin/engineer contact me off list. We have multiple locations receiving DNS queries over UDP where we see the connections making into our server and back out to our CenturyLink edge routers but never completes back to the connecting client at multiple locations. Connections Failing From Digital Ocean NY, Time Warner WI, Rackspace DFW TX (Hartford CT)# dig +short +novc @208.46.135.X domain.com A (Cleveland OH)# dig +short +novc @65.112.236.X domain.com A Connections from Chicago Rackspace to the above locations work as expected. CenturyLink Orlando FL to Hartford CT or Cleveland OH, CenturyLink circuits work as expected. Contact off list for domain and ip information used above. Thanks -- Jason Hellenthal JJH48-ARIN
