Re: Urgent need for bandwidth in Chiswick/London
Does anyone know of any MAN (or anything else for that matter) options at this location? Yes, somebody does know but they are unlikely to be on this list. In general, for any commercial building in any city, there is a building manager who takes care of utilities, air conditioning, heating systems, etc. This person or persons will be aware of any and all telecommunications circuits into the building and which companies send technicians to monkey around with the comms closet. That should be your first port of call. If that person is too hard to get answers from, next best is to talk to neighbouring commercial buildings because MANs are built in rings so chances are that one of the companies connected to neighbouring buildings will also be in yours. Third port of call is to contact the sales departments of all the companies offering MAN services in your city. Since they have a chance to win some business, they will be happy to research their internal records to find out whether or not they have infrastructure in your building. Fourth port of call is your other technical contacts in the city/country in question. And maybe in the fifth position, or lower, is a general mailing list like NANOG. My question is, did you actually go through all the above BEFORE posting to NANOG? --Michael Dillon

I wish abuse was used as intended instead of my every idiot programmer and script writer for their own helpful stuff we never asked for nor does it help us at all nor does it help the users. Unfortunately that is a problem with every public reporting channel. Most 9-1-1 (or your national equivalent) centers report a majority of their calls are non-emergencies. In many cities the police will not respond to automatic dialers calling 9-1-1 because of the extremely high false reporting rate, or put them at a very low, low response priority. Most of the complaints the FCC gets about television and radio programming are from people who have never seen or heard the program they are complaining about. ISP abuse desks, US congressional offices, etc have all implemented things which make contacting them by e-mail harder due to the automatic-idiot problems. There are effective ways to contact your congressional office or ISP abuse desk, and ineffective ways. When they give suggestions about the best way to contact them, its a good idea to listen to what they recommend if you want to be effective. If you just want to complain about ISPs not responding, or the police not finding your stolen car, or 9-1-1 operators refusing calls from your automatic alarm system; you are welcome to continue complaining. It probably won't be that effective, but if it makes you feel better go ahead. On the other hand, if you are interested in accomplishing something then there are different actions you can take.

Re: CWDM equipment (current favorites) (fwd)
As there's no specification for 2.5 gigabit ethernet (that I'm aware of), and SONET gear with pluggable optics is likely out of your league, I'm afraid that's a decision you'll have to make. :-) There are plenty affordable[1] options available 1U for switches with 10GE uplink ports. I've had good luck with the Extreme Summit x450. If you're a bit more daring, Allied Telesyn recently announced a switch with a similar port density, though lacking in the useful bunch of SFPs rather than 10/100/1000 ports configuration. More and more, I'm finding it difficult to justify deploying n x GE port-channels across dark fiber, when 10GE is a lot easier to scale and troubleshoot... Since we are clarifying... Yes, 10G is a nice option when you can use reasonably priced optics (80km). CWDM (nx2.5 or nx1G) works happily up to 30+db of loss and reduces complexity if you can avoid all the associated pieces of DWDM you may need to address conditions in the long reach end of the range.

RE: Yahoo Postmaster contact, please
I have one customer that's been having trouble (not specific to him, all of our ISP subs send out via well-known gateways) and the message started off with 451 Message temporarily deferred - 4.16.50 and the most recent one was Remote host said: 451 Message temporarily deferred - [190]. When I had this problem about 2 weeks ago I could manually initiate a connection to any of Yahoo's MX records and get the first error message. After I filled out the Yahoo! Mail Feedback form on their website (http://add.yahoo.com/fast/help/us/mail/cgi_defer/) I get this response four days later: === Thank you for contacting Yahoo! Customer Care. There appears to have been an incident involving capacity issues within our delivery infrastructure. The error message 451 Message temporarily deferred - 4.16.50 indicates that our MTAs are currently experiencing heavy, unusual traffic. You may retry sending at a later time when you see this message. However please note that emails from the mail server(s) you are using may also have recently become deprioritized due to potential issues with its mailings. These deprioritizations were temporary but may be re-triggered if the sending IP profile continues to be poor. Typically, deprioritizations are triggered by bad individual sender or MAIL FROM profiles. === Googling for some of these error codes yields this Yahoo discussion (http://tinyurl.com/y3nm6p) of a week ago that talks about greylisting and site upgrades, so hopefully this goes away sooner rather than later.

If you're having network connectivity issues reaching Yahoo, NANOG would seem like a reasonable place to raise questions--but this isn't really a list for mail admins to hang out on. It looks like network connectivity between dotorg.org and Yahoo is good, so I'm not sure if there's anything people on this list could help you with--but if you do have network connectivity issues in the future, there's definitely people here who can address those concerns.
