Oh, sure; most muni's contract out the build, and often the day to day operation and customer support load, to a contractor. But that wouldn't really help as much in this case, I don't think; that contract would create an agency relationship, and the contractor would not protect such log data (if it existed, which for L1 and L2 service, it would not as this argument posits it) *from the responsible IT employees of the municipality*.

Looking for success stories in Qwest/Centurylink land
by Joe Maimon 29 Jan '13

29 Jan '13

Anybody have some happy success stories to share about service in Qwest service area post Centurylink acquisition? Unfortunately the ones I have contain more humor than success. Story #1 Ethernet/Fiber service near Tampa ordered via partner, misordered as MPLS, re-ordered as vpls. Delivered by June, I have been trying unsuccessfully to get a MAC off the NID ever since. Similarly, I have been unsuccessful in getting the LEC onsite to troubleshoot the NID. My last update was a due date of 2/22, after they missed a 1/17 date. Nope, not a typo. Story #2 Ethernet/Fiber service in Phoenix ordered via partner. Apparently, in order to save on the expense of the NID/switch combo, the LEC ran the second set of fiber strands up to an existing customer in the building, using dedicated conduit from the building dmarc (which is accessible by our customer). They then instructed us to run copper back from their customer back to our customer's space. This recipient of the new fiber refused permission (not to mention being unhappy at unwittingly providing shared service). LEC claims the order was marked closed and delivered and any changes are new orders that will take 45 days. There has not been an update since, although presumably, we are on the 45 day clock. Due on the 1st, delivered in mid December, this is a month late with no timely resolution in sight. I have been assured by everyone involved that escalation has been pursued to the highest levels, including pleading with the CEO of the unwitting service providing customer, to no avail. If someone from Centurylink who can make things happen and be privy to the real dealings would please reach out directly to me, I have high hopes that there can be happy endings for these stories. Or if anybody has any useful suggestions, ideas, advice, or even commiserations, all are welcome to share. Best, Joe

MessageLabs/MXLogic issues
by Thomas York 29 Jan '13

29 Jan '13

Have any of you noticed issued delivering email through MessageLabs to people who use MXLogic for spam/AV filtering? I've seen it more and more over the last month, to the point that I have to call 5-10 people a day to tell them to whitelist our domain in MXLogic. It isn't specific to a certain domain, just to Symantec/MessageLabs IPs. I've also seen this issue once or twice with domains hosted with Gmail, but those have cleared themselves up. -- Thomas York

RE: switch 10G standalone TOR, core to DC

We use IBM networking (used to be BLADE networks) Rackswitch 8264. They will do TRILL, and have multi-chassis link aggregation, they call vLAG. We use this for cross datacenter aggregation. They do have the L3 features you are looking for and BGP as a possibility, but no full tables. It is a cut-through switch (although this can be toggled in software to store and forward in later switch os). I believe, although I can't find the doc where I read this at the moment, the packet buffer is 2G, but shared among ports. Enterasys S-Series is also an option, but the 10G port densities are much lower. S-Series has large packet buffers, chassis bonding, and L3 features (some modules support full bgp tables).

Slashdot: UK ISP PlusNet Testing Carrier-Grade NAT Instead of IPv6
by fredrik danerklint 28 Jan '13

28 Jan '13

From the article: "Faced with the shortage of IPv4 addresses and the failure of IPv6 to take off, British ISP PlusNet is testing carrier-grade network address translation CG-NAT, where potentially all the ISP's customers could be sharing one IP address, through a gateway. The move is controversial as it could make some Internet services fail, but PlusNet says it is inevitable, and only a test at this stage." http://tech.slashdot.org/story/13/01/16/1417244/uk-isp-plusnet-testing-carr… I'm only here to bring you the news.

What would a Step-by-Step Framework for Planning an IPv6 Deployment Look Like?
by Mukom Akong T. 28 Jan '13

28 Jan '13

Hello all, One of the questions I often get asked during after teaching/facilitating and IPv6 session is: "Now I know all these tech bits and how they come together, but what are the steps for deploying IPv6?" I've often scratched my head because I thought 'that's obvious', however I gave have detailed and have decided to provide a framework that anyone could use and would like to get critiques and suggestions on how to improve this for folks looking how to kickstart their IPv6 deployment project. http://techxcellence.net/2013/01/28/step-by-step-framework-for-planning-ipv… Surprisingly, these are very familiar steps that almost everyone who has done a project in the past can relate to. The steps are: 1. Set Clear Goals for the IPv6 Deployment Project. 2. Identify the List of Tasks Required to Achieve each Goal. 3. Identify Resources Required to Accomplish each Task. 4. Get Management Approval/Sign-off for the Project. 5. Execute the Plan, Documenting Everything as you go. 6. Update Relevant Organisational Processes to Integrate new Capabilities Resulting from the Deployment. These are quite obvious steps, however what each of them means and the thought process required to clarify each is what have detailed. I'd like your comments and also your suggestions on what you can do to move your IPv6 Deployment project from and "incomplete pile of unclear stuff" to and organised set of tasks that will surely lead you towards a working IPv6 deployment? Please share. Regards and have a wonderful week!
