HTTP 302 with multiple Location: headers?
by Jeroen Massar 03 Nov '14

03 Nov '14

Ignoring the fact that Akamai IPv6 is broken on random nodes, thus you get either a working response or not from the same IP as some of the nodes are borked and thus just hang the connection.. (could be pmtu, hard to say without peeking inside the cluster).... see amongst others: https://www.sixxs.net/forum/?msg=general-12378937 But on a non-IPv4 note for once, I just noticed this funny one: $ telnet -4 www.akamai.com 80 Trying 95.101.216.85... Connected to e8921.dscx.akamaiedge.net. Escape character is '^]'.

I think there are a couple of b0rked nodes in the cluster that is attempting to serve me... Greets, Jeroen

Smart Data Pricing Questionnaire
by Gareth Tyson 03 Nov '14

03 Nov '14

Hi everybody, We're doing some research into the use of smart data pricing for enabling cheaper Internet access for the millions in the world who remain disconnected. We basically wish to understand which pricing models for data would be most attractive to network operators, as well as the challenges that might come with them. If you have a spare 10 minutes, it would be great if you could fill out the following questionnaire: https://docs.google.com/forms/d/1B-Vtl3mYJ2TJMWiFXxHySMrKSqxrhy0EzVNDlXKhPe… Many thanks! Best regards, Gareth. --- Dr. Gareth Tyson, CS 404 (Not Found), Electronic Engineering and Computer Science, Queen Mary University of London.

Is it unusual to remove defunct rr objects?
by Tim Howe 03 Nov '14

03 Nov '14

In the recent past, we've had another provider in our same market erroneously advertising prefixes for some of our customers. After we got it cleared up, I noticed that there were some old route objects in RADB that were entered for that provider years ago by 360. These route objects, in a sense, legitimized, the erroneous advertisements by matching the prefixes to that providers ASN. As that provider no longer uses 360/Zayo, I asked Zayo if they could remove the objects. Once the request made it to someone who understood what I was asking, they spent some time and effort over the next few weeks (much appreciated by me, I might add) in hunting down the info they needed to (I assume) manage the old 360 maintnr object. They then removed the offending objects (again, my thanks). One of the Zayo support folks mentioned to me, somewhat apologetically, that it took some time as nobody had ever made such a request before. So this got me wondering: is it really such a rare thing to manage ones route objects such that old defunct data is removed? I'm not under the impression that the issue I had would have been alleviated any by the related route objects having been removed beforehand, but their existence wasn't helping me any either. I've since found a disturbing number of defunct objects that relate to my customers (and me) in a similar way, and I have mostly had success in getting them cleared up. If my relatively small customer base is any indication, there are more incorrect objects out there than correct ones. I feel this is something I should have been looking into sooner. Is this a non-issue that I shouldn't worry about? Doesn't the quality of this data effect Origin Validation efforts? Sorry that this turned out so long; I wanted to give some context. --TimH

Industry standard bandwidth guarantee?
by keith tokash 02 Nov '14

02 Nov '14

Hi *, sorry if this has been answered, I did look. Is there an industry standard regarding how much bandwidth an inter-carrier circuit should guarantee? Specifically I'm thinking of a sub-interface on a shared physical interface. I've not thought much about it but if there's a more generally-accepted guideline than, "when the customers start leaving / when you leave," I'm at least 5% ears. Thanks, Keith

Hello, I'm curious what is the "tools" for computing and validating TE tunnels over the network. I read on MPLS Enabled Applications that there are tools out there that can be used to do so.
