Google SMTP acceptance policy?
by Jonathan Traylor 06 Nov '08

06 Nov '08

Anyone have guidance on how to legimately stay out of Google/GMail's spam classifier and arrive at the inbox? We have a domain that is relatively newly registered, has proper MTA configuration and SPF records that I haven't been able to find on any blocklist, but GMail sends email from it straight to the spam folder. I haven't been able to find useful documentation for GMail in this regard around the web. Have looked at abuse.net's info, links and resources. Thanks, -- Jonathan

Sprint v. Cogent, some clarity & facts
by Patrick W. Gilmore 06 Nov '08

06 Nov '08

Having skimmed the Sprint / Cogent threads, I saw multiple errors and lots of really bad guesses. Instead of replying individually, I thought I would sum up a few facts so everyone was on the same page. This way when we run off into another 100 post thread, we can at least -start- from reality (although I would bet serious cash on long odds we will diverge from it soon enough). 1. Neither Sprint nor Cogent have transit Both Sprint & Cogent are transit-free networks. (Notice how I carefully avoided saying "tier one"?) Whether one or both _should_ have transit is not a fact, and therefore outside the scope of this e- mail, but that neither have transit today is a fact. (And please don't tell me how Network X has 100 Mbps of transit in Sri Lanka because they are too lazy to lease undersea cable. If you don't understand what I am saying here, stop reading now.) 2. The Internet cannot "route around" de-peering I know everyone believes "the Internet routes around failures". While occasionally true, it does not hold in this case. To "route around" the "failure" would require transit. See item #1. 3. Standard transit contracts do not guarantee full connectivity If you are a Cogent customer, it is very unlikely your contract will allow you SLA or other credits for not being able to reach Sprint unless you negotiated something special. I doubt Sprint's standard contract is much different. Transit contract SLAs end at AS boundaries. This is because Network A has no control over Network B and therefore will not give credit if Network B fails. Of course, you can still sue, threaten to terminate, etc., but the letter of the contract almost certainly says nothing about packets going beyond your transit provider's ASN. 4. There is a reason behind ratios which has nothing to do with telco "sender-pays" Hot potato routing + very poor ratios puts much more of the cost on the receiving network. This is a valid, logical, and costly concern for receiving networks. The concern can be alleviated by cold-potato routing through accepting MEDs, anycast, CDN, and other technologies; to which the receiving network may say they cannot send proper MEDs, etc. Whether the problem can or should be worked through is not a fact, though. That this issue has nothing to do with telco "sender- pays" mentality is. (Of course, the telcos might still have that mentality, but that doesn't change the facts.) 5. Cogent has been disconnected several times Cogent has been de-peered (e.g. Teleglobe, L3, Sprint) and/or performed de-peering themselves (e.g. Telia) multiple times. Cogent has been disconnected from another network more times & for longer (in each instance?) than every other transit free network combined for the last decade. (In fact, if memory serves, for the history of the Internet - but I'm not quite sure enough to guarantee it as fact.) Cogent has also de-peered many non-transit-free networks, at least sometimes without even notifying the peer prior to disconnection. Whether that makes Cogent the bully-er or the bully-ee is not fact, so I will not comment on that here. There are probably other errors I missed while skimming the longer posts. But this should get us started on a good, clean, factual footing for future flights of fancy. -- TTFN, patrick

Ixia, Juniper going green?
by Glen Kent 06 Nov '08

06 Nov '08

http://www.lightreading.com/document.asp?doc_id=166871 I wonder what impact this would put on other vendors to turn down their power consumptions and turn, as Juniper and Ixia like to put it - Green! BTW, the specs are a little skewed because they're only measuring power consumption when the router is only forwarding traffic, i.e., there is no traffic going to CPU. Also any idea about the genesis of this ECR initiative (http://www.ecrinitiative.org/) and what their eventual goal is ? Glen
