by Anurag Bhatia 13 Sep '12

13 Sep '12

Seems like Softlayer/Network layer having rouitng glitches in Asia. Their prefix 216.12.192.0/19 is not working in South East. Route goes till Singapore router and times out there. traceroute to hostgator.com (216.12.194.67), 30 hops max, 60 byte packets 1 router.local (192.168.1.1) 1.576 ms 2.025 ms 2.508 ms 2 117.212.40.1 (117.212.40.1) 26.500 ms 29.397 ms 31.717 ms 3 218.248.173.46 (218.248.173.46) 35.014 ms 36.184 ms 38.806 ms 4 115.249.245.198 (115.249.245.198) 50.224 ms 54.037 ms 56.476 ms 5 115.255.252.149 (115.255.252.149) 100.129 ms 101.235 ms 106.338 ms 6 62.216.147.249 (62.216.147.249) 115.066 ms 116.228 ms 118.407 ms 7 ge-1-0-0.0.cjr02.chn001.flagtel.com (62.216.135.226) 121.183 ms 83.215 ms so-7-0-0.0.ejr03.sin001.flagtel.com (62.216.128.73) 116.212 ms 8 so-7-1-0.0.ejr04.sin001.flagtel.com (62.216.128.153) 116.677 ms 118.551 ms 62.216.128.246 (62.216.128.246) 121.665 ms 9 p6453.sgw.equinix.com (202.79.197.19) 162.612 ms 163.006 ms 163.631 ms 10 ae12.bbr01.eq01.sng02.networklayer.com (120.29.215.102) 167.409 ms 169.761 ms 173.955 ms 11 ae6.dar02.sr03.sng01.networklayer.com (50.97.18.203) 177.675 ms 180.009 ms ae5.dar02.sr03.sng01.networklayer.com (50.97.18.199) 171.207 ms 12 po2.fcr01.sr03.sng01.networklayer.com (174.133.118.133) 180.555 ms * * 13 * * * 14 * * * I wonder what causes such issues? Clearly issue is within Softlayer's AS 36351. So is it like broken OSPF inside or iBGP? -- Anurag Bhatia anuragbhatia.com Linkedin <http://in.linkedin.com/in/anuragbhatia21> | Twitter<https://twitter.com/anurag_bhatia>| Google+ <https://plus.google.com/118280168625121532854>

Google / Gmail SSL write errors
by Paul Kelly :: Blacknight 12 Sep '12

12 Sep '12

Hi All, Are any of you (that use Exim as their MTA) having SSL write errors in your exim logs when delivering e-mail to Gmail or Google addresses? it seems limited to Exim as we've got a lot of other MTAs that have no issues. it also appears to be specific to emails with attachments... Anyone aware of changes G have made regarding TLS delivery?

Re: The End-To-End Internet (was Re: Blocking MX query)

----- Original Message ----- > From: "Owen DeLong" <owen(a)delong.com> > I am confused... I don't understand your comment. It is regularly alleged, on this mailing list, that NAT is bad *because it violates the end-to-end principle of the Internet*, where each host is a full-fledged host, able to connect to any other host to perform transactions. We see it now alleged that the opposite is true: that a laptop, say, like mine, which runs Linux and postfix, and does not require a smarthost to deliver mail to a remote server *is a bad actor* *precisely because it does that* (in attempting to send mail directly to a domain's MX server) *from behind a NAT router*, and possibly different ones at different times. I find these conflicting reports very conflicting. Either the end-to-end principle *is* the Prime Directive... or it is *not*. Cheers, -- jra -- Jay R.

SAVVIS IPv6 Status
by Christopher J. Pilkington 11 Sep '12

11 Sep '12

We're in SAVVIS DC3 and wondering what the status of IPv6 is there. We submitted a request for IPv6, and we were told SAVVIS does not assign address space. Later emails we were told they will route IPv6 however. I haven't yet contacted sales... I think we lost our rep in the CenturyLink merger. I did see some blurbs from last year saying they weren't ready at that time. Was hoping this changed. We're not multihomed there, (except indirectly via through SAVVIS' own upstreams), so I don't think I can justify an ARIN assignment for that site. Replies on or off list welcome. Thanks much! -cjp

Traffic Burstiness Survey
by Monia Ghobadi 11 Sep '12

11 Sep '12

Dear Nanog members, I am a PhD student at University of Toronto and I am working on traffic burstiness in data centers. In the following I am asking two questions to raise motivation for my research. I appreciate if anyone could answer these questions to their best knowledge. *The questions are:* 1) ‘Bursty’ is a word with no agreed meaning. How do you define a bursty traffic? 2) If you are involved with a data center, is your data center traffic bursty? -- If yes, -- Do you think that it will be useful to supress the burstiness in your traffic? (For example by pacing the traffic into shorter bursts) -- If no: -- Are you already supressing the burstiness? How? -- Would you anticipate the traffic becoming burstier in the future? Thanks, Monia ------------------ Monia Ghobadi PhD Student University of Toronto http://www.cs.utoronto.ca/~monia/
