Data Center Installations

Do any of you have a "go to" resource for materials used in installations? Tie wraps, cable management, blahblahblah? I have found several places, but I'm curious to know what the nanog ninja's have to say. //warren

Traffic shaping going on?
by Ray Wong 08 May '13

08 May '13

Doesn't seem directly correlated with outages, and everything seems to be working ok, but I'm seeing about a 20-30% shift in flows from AS7792 to AS3356. Seems unlikely that many ISPs have suddenly turned up a level3 link on the same day/hour, and performance metrics all seem normal. I confess I've had to turn my attention away from network issues to systems/DB/security ones lately, so I may have missed something. Anyone else seeing fairly significant next hop shifts over the previous 24 hours? All of yesterdays major outages I was sort of suspecting seem to have been resolved without correlating shifts back. -R>

NANOG58 bad helo for hotel reservation emails
by Robert Drake 08 May '13

08 May '13

Sorry for the noise, but I thought this might be of interest to anyone waiting for their hotel confirmation: NOQUEUE: reject: RCPT from feport01.hiltonhhonors.net[63.122.201.171]: 450 4.7.1 <ironport.hhonorscrm.net>: Helo command rejected: Host not found; from=<waldorfastoriahotels&resorts(a)res.hilton.com> to=<excised> proto=ESMTP helo=<ironport.hhonorscrm.net> So if you run your own server and/or are capable of compensating for a misconfigured MTA, you should add an exception for feport01.hiltonhhonors.net.

CenturyLink Outage?
by Jason Lester 07 May '13

07 May '13

Does anyone know what is going on with the nationwide CenturyLink outage? Their NOC recording says it is a BGP routing issue with their upstream peers affecting Internet traffic and traffic between regions. Our outside connectivity with them has basically been down since about 4:00AM (EDT) this morning. The prefixes we were receiving from them were fluctuating between a few hundred and a few thousand all morning. We are getting the full BGP table from them now (for about the last hour), but still not seeing any incoming traffic. Seems like a major issue since it has been almost 9 hours now.

NANOG58 parking
by Jeff Wheeler 05 May '13

05 May '13

I noticed that some folks were unhappy with the parking fee in Orlando. The Roosevelt New Orleans, for NANOG 58, tells me that the only on-site parking is valet for $42/day. Anyone planning to drive or stay at a different hotel may want to consider that in advance. -- Jeff S Wheeler <jsw(a)inconcepts.biz> Sr Network Operator / Innovative Network Concepts

HTTPS-everywhere vs. proxy caching
by Jay Ashworth 05 May '13

05 May '13

It occurs to me that I don't believe I've seen any discussion of the Unexpected Consequence of pervasive HTTPS replacing HTTP for unauthenticated sessions, like non-logged-in users browsing sites like Wikipedia. That traffic's not cacheable, is it? Proxy caches on services like mobile 3/4G, or smaller ISPs, or larger corporations can't cache it, I wouldn't think, which means both that they will see traffic increases, and that the end sites will as well. Has this been discussed and I missed it? Do I improperly understand transparent caching? Or is this just a bomb waiting to go off? I assume that Wikipedia themselves are on top of the idea that their in-house reverse-proxies won't be carrying that traffic (though I don't actually know what their architecture looks like anymore), but..
