Re: Bandcon

Hi All, My name is Todd Braning, I work on the technical side of the BandCon house. I am afraid Paul's email is inaccurate. Here are a few facts: BandCon offers transport services that can be configured as unprotected or protected. If you buy an unprotected circuit, and the underlying transport has issues, your VC will have issues. However that is not the case if you purchase a protected service. BandCon does not "just slap all your locations into one big VLAN and let unknown unicast flooding and MAC learning sort it out". All circuits are provisioned as separate point to point MPLS VCs. We do, in fact, utilize traffic engineering and do not oversubscribe our wavelengths. Regarding our NOC. It is true that in the past, our NOC was sub par. This is no longer the case. About a year ago we replaced all NOC technicians, brought in an experienced NOC manager and have made significant progress. Paul - I cannot find you in our customer database so I am not sure what services you bought from BandCon. However, I would be happy to speak with you, or anyone else interested, regarding the technical merits of our transport services. If anyone is interested, please contact me. Thanks, Todd Braning

Bandcon
by keith tokash 09 Jul '09

09 Jul '09

We've run our circuits pretty hot and not noticed anything that would indicate a lack of shaping/policing. And while the flame war with the attrition guys was pretty funny (I'm a sucker for classics) I wouldn't really use that as any type of barometer of ... well anything really. This email may be accurate, but I'll pretend I'm an engineer for a moment and ask for something to back up allegations before I believe them. Even with the internet's stellar reputation for accuracy via intuition. --- Keith Tokash, CCIE #21236 Network blah blah blah, Myspace.com -----Original Message----- From: Paul Wall [mailto:pauldotwall@gmail.com] Sent: Thursday, July 09, 2009 11:50 AM To: Robin Rodriguez Cc: nanog(a)nanog.org Subject: Re: Bandcon On Wed, Jul 8, 2009 at 11:52 AM, Robin Rodriguez<rrodriguez(a)ifbyphone.com> wrote: > I don't have any usage experience, but would be very interested from anyone > who does as well.

I do wonder how they can undercut everyone's price by such a > margin. Were you seeing great quotes into non Equinix facilities? Simple, they're oversubscribing their transport circuits and letting users fight for bandwidth. Basically what they're doing is buying a 10GE unprotected wavelength from a carrier, dropping a switch on the ends, and loading up multiple customer VLANs onto the circuit. There are no bandwidth controls, no reservations, no traffic engineering, nothing to keep and the circuit uncongested, and these are unprotected waves so they go down on a regular basis whenever their carrier does a maintenance. How they implement multi-point service is even scarier, they just slap all your locations into one big VLAN and let unknown unicast flooding and MAC learning sort it out. Most serious customers run screaming, I'm sure you can find some former customers who can describe the horror in more detail off-list. When things break, their support is nothing to write home about. They often brag that they have a former Level3 engineer on payroll, unfortunately he's nowhere to be found, and their suport people aren't terribly sharp on those rare occasoions when they *do* answer the phone or respond to e-mail. Like someone else pointed out, multi-day outages aren't at all uncommon, so if you end up going with Bandcon, make sure you have sufficient redundancy in place. Since they can't really compete on quality, they compete instead on price. Their sales force spams and cold-calls every website, ARIN, peeringdb, etc on a regular basis, and can't take "no" for an answer. The following exchange sums it up nicely (warning: foul language): http://attrition.org/postal/z/034/0931.html They are currently running a $2.50/mg transit promotion, which makes me wonder how they're doing on their Level3 and Global Crossing bandwidth commits and whether or not they're solvent.

Level 3 - "legacy" Wiltel/Looking Glass bandwidth
by Scott Howard 09 Jul '09

09 Jul '09

We're looking at getting connectivity via Level 3 in a particular datacenter, but we're being told that it's "legacy Wiltel/Looking Glass" rather than "true" Level 3. Given that both of these acquisitions occurred years ago should I be worried, or is this "legacy" connectivity the same as L3 at any other datacenter? Scott.

Does anyone have any data on how the memorial event for Michael Jackson effected the global backbones? This was seen as another inaugural type of traffic day to most of the people I've talked to. -S

Hi, I've seen a big drop in IPv6 traffic volume on our Freenet6 IPv6 service last night and it seems to be the same on AMS-IX. Has anyone else seen the same? Any idea why? Thanks, Mikael

Call for Presentations - AusNOG-03
by David Hughes 09 Jul '09

09 Jul '09

Call for Presentations - AusNOG-03 --------------------------------- AusNOG-03 is to be held in Sydney, Australia between 31st August and 1st of September 2009 The AusNOG meeting provides the Australian community with a forum to exchange information and experiences on a number of issues relating to the operation and support of networks, with a specific focus on the coming 6-12 months. The conference is expected to have a strong technical representation from companies operating networks in Australia. Details of AusNOG-03 and past meetings can be found on the AusNOG web site at www.ausnog.net. Submissions ------------ Please read the information below carefully. Send your proposed topics and details to organisers(a)ausnog.net. Please include a detailed overview including the expected length and technical depth of your presentation. The program committee will confirm your application and may get back to you with any questions. Please remember this is a technical event for network operators and presentations should be representative of this. Marketing presentations or presentations focusing on specific products are not suitable for this event. Some areas of current interest to the target audience are listed below. These are simply suggested topic areas and the committee will happily consider proposals for papers covering any facet of network technology, network operation, or the industry. 1. NBN Technology. High speed access, core, edge, border... Access speeds measured at 100M will present all sort of challenges across the provider sphere. As so much is yet unknown how the NBN will land on us, will there be the ability to specify the edge device or policy. Either way talks on experience in this space is what we are seeking. 2. Backhaul. Increasing end user speeds in an NBN world will see a requirement for increased backhaul. How do you implement a multi hundred gigabit backhaul network ? What are the issues for wholesale play with this type of undertaking ? 3. Content to the Edge. Whilst we are about to enter the work of real competition in international access and bandwidth is about as inexpensive as it has ever been we are still a small population very far away from the main Internet trade routes. Experience with CDN, distributed content applications and how operators leverage servers, DNS, load balancers etc to bring about an outcome. 4. Operational Best Practices. Tools, methodologies and techniques that can improve the reliability and efficiency of IP Networks. Configuration management, configuration automation, routing registries, performance monitoring and availability monitoring are always of interest to operators. 5. Regulatory, Market Data and Overseas Trends (Regulatory and Industry Bodies Updates, Market Data and Statistics, Trends from Overseas Markets) Panel Discussions ----------------- - Required Panellists: 8-10 - Panel Length: 45 mins - Number of Panels: 2 Panels are the interactive part of the conference. The job of Panellists will be to stimulate and moderate the discussion. Whether you are on the panel or in the audience your input would be appreciated. The two Panel Topics will be related to the industry at the time of the conference. Propose a topic that you think will be interesting, or if you think you are interesting, propose yourself for inclusion to the panel :-) Keynote Addresses ----------------- - Required Speakers: 2 - Presentation Length: 45 mins - Number of Topics: 2 We are seeking 2 speakers for Keynotes Addresses. Each Keynote will be of 45 mins in length, including time for input from the industry. If you would like to be considered for a Keynote topic, please email organisers(a)ausnog.net with details of yourself and your topic. Important Dates --------------- - 10 July 2009 - Call for Presentations Opens - 26 July 2009 - Deadline for Proposals - 3 August 2009 - Response to presentation proposals - 10 August 2009 - Draft program published to website - 17 August 2009 - Final program published The AusNOG-03 Organisers ...

GoDaddy issues this morning?
by Sean 08 Jul '09

08 Jul '09

Anyone know what was the deal with GoDaddy this morning? I sporadically could not resolve a domain I own this morning. Checked the authoritative and it was fine... then noticed that it was completely not working from some ISPs but OK from others, etc. Went to GoDaddy's site and finally saw a small notice on their support page saying they were having issues with Verizon customers on the east coast. Well, I'm in Illinois and I certainly don't consider this the east coast, however some people I know on a Verizon DSL account could not resolve any of the domains I had registered on GoDaddy. Also, results from a L3 DIA were sporadic as well. I really didn't have much time to look at it this morning and now the notice is gone from their site so I assume it's fixed...? Anyone shed some light on this? Registrar issues are so rare IMHO, Verizon routing issues on the other hand, I'm not really sure about as I live in AT&T/Comcast country. -Sean

Re: [SPAM-HEADER] - Re: Point to Point Ethernet - Email has different SMTP TO: and MIME TO: fields in the email addresses

> The reality is that is an SDH/SONET backbone underlying most of these Ethernet networks. That may be so (however, numbers for the national provider I work for do not tend to bear this out). But does it matter? People presumably use Ethernet because it is inexpensive, easily available, well known, etc. Yes, if the underlying technology is SDH *or* DWDM with an SDH type interface, I know *I* would prefer to use the SDH interface - because it gives me the SDH OAM we all know and love. But if my router vendor charges me a 10-30% premium for using cards with an SDH interface, then Ethernet is going to win every time... There are vendors that supply cards where the optics can be reconfigured for 10Gig Ethernet LAN *or* WAN (SDH) interface, and where you don't have to pay a premium. The Juniper MX series is an example. But real SDH cards with the corresponding lower encapsulation overhead still come at (high) price. Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no
