whois.internic.net / whois.crsnic.net IPv6 timeouts
by Stephen Frost 10 Jul '13

10 Jul '13

All, Don't know if it'll help or if this is simply old news to most, but the whois systems (whois.internic.net/whois.crsnic.net) have AAAA records and happily answer TCP/43 requests w/ the usual blurb, but all the servers I've hit then fail to actually provide data and instead the whois client (Ubuntu 13.04) simply time-outs. sfrost@tamriel:/home/sfrost> whois -h 2001:503:5ae2:1060::74 networksolutions.com Whois Server Version 2.0 Domain names in the .com and .net domains can now be registered with many different competing registrars. Go to http://www.internic.net for detailed information. Timeout. Servers that I've tried so far (all IPv6 addresses I got through running 'host whois.crsnic.net'): 2001:503:5419:1060::74 2001:503:3227:1060::74 2001:503:6810:1060::74 2001:503:bfb0:1060::74 2001:500:30ff:1060::74 2001:503:7bbf:1060::74 2001:502:be98:1060::74 2001:502:8c25:1060::74 Anyone from NetSol care? It's not the end of the world, but it certainly is quite annoying.. Judging by some complaints on the 'net, looks to be a rather long-standing issue too (there's a Debian bug #683187 which mentions similar issues from nearly a year ago..). Thanks, Stephen

google troubles?

I can see the Google IP space (64.71.240.0/20) from Verizon/AS701, but not from Rogers/AS812 in Toronto. I've done a few other test traceroutes through Rogers to verify that they didn't filter UDP/ICMP. At this point nothing would surprise me from Rogers.

Diverse sub-sea carrier links London / Tokyo
by Rodrick Brown 10 Jul '13

10 Jul '13

I'm looking for a diverse carrier circuits to/from the following POP's over different sub-sea links. I'm not too comfortable getting diverse path(s) from the same carrier (Hibernia) so I'm interested in getting input from others who have dealt with other carriers in these locations who can offer connectivity over different sub-sea links than my current provider. 755 Secaucus-350 Cermak-Seattle-*PC1 Cable*-Ajigaura-TY3 (Equinix) 755 Secaucus-300 Blvd-111 8th-*AC1 Standard*-Slough-Telehouse North-London Hosting Center (Savvis) Sorry if this is off-list. --RB

Seeing lots of reports of people unable to get to many Google services. Seems to be affecting Comcast users disproportionately. It's fine for me, but a lot of my staff are basically out of luck...but according to the Google Apps Status page, everything is fine. It's anecdotal, but it would seem like there's an issue based on these reports. Oh, and this: http://www.cnn.com/2013/07/10/tech/web/google-down/index.html Anyone know what's up? Fiber cut? DC outages? -- blair

www.att.net ipv6 traceroute

Anyone else noticing odd ipv6 traceroutes to www.att.net (2001:1890:1c01:2::40)? For example, the first traceroute originating in Chicago, and if the hostnames are anything to go by: Chicago -> Dallas -> Atlanta -> Miama -> NYC -> Amsterdam -> Frankfurt -> France -> D.C. -> Atlanta... The first 2 traceroutes are on SixXs tunnels and the third is native.

What to expect after a cooling failure
by Erik Levinson 10 Jul '13

10 Jul '13

As some may know, yesterday 151 Front St suffered a cooling failure after Enwave's facilities were flooded. One of the suites that we're in recovered quickly but the other took much longer and some of our gear shutdown automatically due to overheating. We shut down remotely many redundant and non-essential systems in the hotter suite, and transferred remotely some others to the cooler suite, to ensure that we had a minimum of all core systems running in the hotter suite. We waited until the temperatures returned to normal, and brought everything back online. The entire event lasted from approx 18:45 until 01:15. Apparently ambient temperature was above 43 degrees Celcius at one point on the cool side of cabinets in the hotter suite. For those who have gone through such events in the past, what can one expect in terms of long-term impact...should we expect some premature component failures? Does anyone have any stats to share?

I have seen DDR2 RAM give random errors from inadequate cooling. The cabinets were stacked to the max with severs but the doors were not meshed. DDR2 run fairly hot, especially when all the banks are filled.

Does anyone have any stats to share? If the HDDs were spinning while above rated maximum ambient intake temp, *especially* if they're not *right out front in the intake path* (is anything not built that way anymore? Yeah; the back side of 45-drive Supermicro racks, among other things), you should probably plan on doing a preemptive replacement cycle, or at the very least, pay *very* close attention to smartctld, and have a good stock of pre-trayed replacements. Remember that you may fall in the RAID Hole if you wait for failures, and hence lose data which isn't backed up anyway -- if more drives in a raid group fail *during rebuilds*, you're essentially screwed. If your raid groups were properly dispersed across drive build dates, then this will probably be *slightly* less dangerous, but still. Also watch bearing-type fans. Cheers, -- jra -- Jay R.

I've been seeing really bad packet loss between PCCW and frontier, and so far haven't been able to make any traction with anyone on either side. I'm betting that the ??? is a peering point either in London or Ashburn. uk.bgp4.net (0.0.0.0) Tue Jul 9 20:39:53 2013 Keys: Help Display mode Restart statistics Order of fields qu it Packets Pings Host Loss% Snt Last Avg Best Wrst StDev 1. 212.111.33.230 0.0% 43 1.7 0.7 0.5 1.8 0.3 2. 212.111.33.237 0.0% 43 2.3 1.9 1.1 22.7 3.3 3. 63.218.13.221 0.0% 43 2.3 15.6 1.1 230.3 45.9 4. ??? 5. 74.40.2.173 23.3% 43 177.9 150.3 147.8 177.9 7.0 6. 74.40.2.193 20.9% 43 149.9 149.9 149.1 161.2 2.1 7. 74.40.3.241 18.6% 43 149.6 152.4 149.1 193.2 8.8 8. 74.40.5.49 28.6% 43 148.1 150.8 147.8 192.1 9.9 9. 74.40.5.54 26.2% 43 148.3 150.5 147.9 218.7 12.6 10. 74.40.5.46 33.3% 42 149.5 154.0 149.2 212.8 14.0 11. 74.40.3.137 16.7% 42 147.4 148.7 146.9 163.0 4.1 12. 74.40.1.154 29.3% 42 148.2 153.6 147.7 206.7 14.2 13. 50.34.2.162 35.7% 42 150.2 150.4 149.8 156.3 1.2 14. 50.46.150.55 26.2% 42 150.7 151.0 150.5 152.0 0.4

Does anyone have any stats to share? No stats, but way back in the day of very large computers (1 each) in very large facilities, it seems like the thing we worried most about at restart was too-rapid cooling and the resulting condensation if the conditions were right. After power-up the next thing was disk crashes that occurred on the way down (this was a long time ago discs and drums are different now). Lastly was overheat failures which were relatively few and always in components with a weakness reputation. -- Requiescas in pace o email Two identifying characteristics of System Administrators: Ex turpi causa non oritur actio Infallibility, and the ability to learn from their mistakes.
