TWC (AS11351) blocking all NTP?
by Jonathan Towne 08 Feb '14

08 Feb '14

This evening all of my servers lost NTP sync, stating that our on-site NTP servers hadn't synced in too long. Reference time noted by the local NTP servers: Fri, Jan 31 2014 19:11:29.725 Apparently since then, NTP has been unable to traverse the circuit. Our other provider is shuffling NTP packets just fine, and after finding an NTP peer that return routed in that direction, I was able to get NTP back in shape. Spot checking various NTP peers configured on my end with various looking glasses close to the far-end confirm that anytime the return route is through AS11351, we never get the responses. Outbound routes almost always take the shorter route through our other provider. Is anyone else seeing this, or am I lucky enough to have it localized to my region (Northern NY)? I've created a ticket with the provider, although with it being the weekend, I have doubts it'll be a quick resolution. I'm sure its a strange knee-jerk response to the monlist garbage. Still, stopping time without warning is Uncool, Man. -- Jonathan Towne

Odd Cogentco routing?

Hello - While doing some traceroutes, I have found a few destinations that I found a little odd. For example: 5.|-- bbr01aldlmi-bue-2.aldl.mi.charter.com 0.0% 60 152.1 47.2 8.3 367.6 66.0 6.|-- bbr01sgnwmi-bue-5.sgnw.mi.charter.com 0.0% 60 102.3 53.4 15.6 317.9 66.3 7.|-- be4041.nr21.b016069-0.dtw04.atlas.cogentco.com 0.0% 60 78.9 58.3 19.6 267.9 62.1 8.|-- te0-5-0-5.rcr21.dtw04.atlas.cogentco.com 0.0% 60 32.6 58.2 20.3 218.3 54.6 9.|-- te4-2.ccr01.tol01.atlas.cogentco.com 0.0% 60 359.6 95.2 21.4 359.6 84.5 10.|-- te0-5-0-1.ccr21.cle04.atlas.cogentco.com 0.0% 60 24.3 70.0 24.3 219.3 52.5 11.|-- te7-2.ccr01.buf02.atlas.cogentco.com 0.0% 60 29.3 89.9 28.8 245.4 66.0 12.|-- te7-2.ccr01.yhm01.atlas.cogentco.com 0.0% 60 117.6 105.0 30.6 467.8 87.7 13.|-- te0-7-0-34.ccr21.yyz02.atlas.cogentco.com 0.0% 60 167.5 65.8 32.0 316.7 51.7 14.|-- level3.yyz02.atlas.cogentco.com 15.0% 60 132.0 91.2 47.6 326.1 57.9 15.|-- ae-13-13.bar1.Toronto1.Level3.net 61.7% 60 62.4 107.9 49.5 282.7 73.0 16.|-- ae-9-9.ebr1.Chicago1.Level3.net 0.0% 60 92.4 116.8 69.6 315.0 59.2 17.|-- ae-1-100.ebr2.Chicago1.Level3.net 1.7% 60 92.3 127.7 71.2 370.1 62.1 18.|-- ae-3-3.ebr2.Atlanta2.Level3.net 0.0% 60 74.6 125.5 70.7 261.0 50.3 19.|-- ae-2-52.edge4.Atlanta2.Level3.net 0.0% 60 75.0 121.0 71.0 252.4 45.6 Detroit -> Toledo -> Cleveland -> Buffalo -> Hamilton, ON -> Toronto -> Chicago.. Is it odd that Cogentco is routing USA traffic to Canada and handing it off there to Level3 just to bring it back in to the USA? There is also some packetloss at the exchange... Thanks, David

Well when industries don't self regulate governments step in. This industry is demonstratably incapble of regulating itself in this area despite lots of evidence of the problems being caused for lots of years. This has been DOCUMENTED BEST CURRENT PRACTICE for 13.5 years. Everybody else is having to deal the problems caused by these bad actors. Hell, I suspect you could send the directors to gaol or make them pay a heavy fine today by properly examining the existing laws. A new law would just make the problem more explicit.
