Actually, when you count the number of countries directly interconnected at any Asia Pacific IX (including the ones on the US West Cost) STIX - Singapore Telecom Internet Exchange is currently #1. (see http://www.stix.net) Singapore's SBA (the Internet censor) has stated over and over again that business and international traffic are NOT their problem. They just out to protect the people at home - and that's Singapore's really none of our business (and not a topic for NANOG). Please read the information from the source vs reading biased reporters from the US - http://www.gov.sg/sba. As to you other point, AP CIX is a no go in Asia Pacific. This discussion as been going on for over 4 years. I've been involved and actively trying to make it happen for over 3 years. The cable consortium, telco, national, AP ISP and US ISP politics prevent any type of successful 'neutral' IX in Asia Pacific.

And neither did the United Way study, nor the several others that I remember reading.... This is _very_ well established, folks. The US IRS is a model of efficiency for fund raising, with far less distributed overhead than others, and a budget of 1/10,000 (off the top of my head) of collected revenue. Compare with sales or property tax, with their thousands of separate administrations, and own elected officials, etc. I have read that groceries actually _like_ to get food stamps. They put big signs on their windows "food stamps accepted here". They are much easier and cheaper to administer than manufacturers' coupons. (As an aside, related to my later recycling note, groceries _hate_ recycling, which would _not_ happen without government enforcement.) > Most of what charities spend is cost of fundraising. > That's correct, for many! > When you figure _that_ in, you'll get government efficiency well > below that of any private organization. > This comment makes no sense, as it is pretty obvious that government does not spend most of its budget on fund raising, and therefore your conclusion is at variance with your own assertions.

Folks, I just gave a few of the well-documented examples of when it is more efficient for the people to form a collective organization (called government) than to privatize.

Our Internet is a fine example of what government and academics _can_ do. And Internet II may very well be a boon to the world, if it can provide impetus for development of new technologies.

Of course it remains to be seen what will happen in HK next July, but note that HK has a reasonable sized nap already. The HKIX. My understanding is that they are about to upgrade the exchange to an ATM switch. (whatever) However, I had huge problems running an ISP in HK. The telco pricing has always been such that it is scads less expensive to connect back to the US than to another country, even another country just a few miles away. I keep watching the pricing and goings-on to see if/when there will be a reasonable pricing decrease on bandwidth to Asia, but haven't seen anything yet. I'd love to see someone get an oc3/12/48 pipe from HK to the west coast, and resell to the 60+ HK ISPs at reasonable prices. While in HK a week ago, I was trying to set up a 128K line for a small organization there. The cost is in the US$4k range -- I was afraid to tell those guys what I pay for a 128K bri line here in the US. For the time being, it seems that the most affordable solution would be for each country to build it's own exchange, and have everything link back via the US. (although its silly to have traffic from HK to Bangkok routing via San Jose...) If someone has more recent or more optimistic info, please let me know! davec

>I suggest that neither gleefull hand-rubbing nor "obvious" pronouncements >based on partial knowledge about the real situation will seem quite so >appropriate when it's *your* turn to be downfield from the launcher. Don't forget 500 year floods that happen twice in a couple of years, e.g. the midwest. Or the occasional bombing, e.g. our New York City POP is in Hackensack, NJ now, the MIDNET router in Oklahoma City is in a landfill now. An Internet connection is pretty far down on the list of important things in a real disaster. Stuff happens. No one can predict or plan for everything. But you can have procedures in place to combat the biggest problem in diasasters, poor communication. Partial knowledge about the real situation happens when the real information isn't made available. Techies sometimes get too wrapped up in the hardware, redudant fiber, generators, bomb-resistant shelters; and forget about keeping people informed. It also works to your advantage to keep people informed. They tend to be more understanding, and willing to give you time when they know the situation, and that you are dealing with it. But you only get one free pass. Non-statement statements tend to fan the flames. I think I've said all this before. BBNplanet is better than many ISPs, once you find out the ticket number. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

I did not say multi-homing by itself would be a cure-all. I picked Sun as an example among the affected customers because they do have several interconnected physical locations in the bay area, US-wide and abroad and also in-house expertise on routing. It is just that a whole bunch of smart people running Sun's NOC must have felt helpless.. If only they had a pipe going out to somewhere else, another provider in the bay area in this case, they could have reconfigured routers and minimized the hit. In hindsight, solutions to tolerate a given failure are very easy to come by but shouldn't be talked down. I did not blame BBN--shit happens--but I wouldn't assume that their NOC is necessarily designed to be more fault tolerant than what a smaller ISP can or what the people at Sun could if they didn't somehow assume IP transit out of BBN was fault tolerant enough. For all you know, Sun might have multiple pipes connecting to BBN, multipe routers and CSU/DSU spares. I know for sure a client of BBN's cupertino POP was affected because all BBN traffic in the bay area, as far as I can tell, went/goes through the stanford location. Sanjay.
