Aussie Telco Lays New Fiber For Microsecond Trading Boost

schliz writes "Australian data center and telecommunications provider Vocus has installed two new underwater fiber links across the Sydney Harbor in a bid for the lowest connection latency between the city's financial district and the Australian Securities Exchange's recently opened data center, north of the CBD. The project involved 1.6 kilometers of custom, 312-core single-mode optical fiber cable, and was expected to deliver a route that is 400 meters shorter than existing links. RTFA for pretty installation photos."

      So how many bankers are willing to donate a couple hundred million dollars to improve the education system, so that people understand that an adjustable-rate mortgage is not something that will work in their favor?

      Huh? An ARM is not advantageous? Since when? I'm pretty sure I read about a study claiming that there has never been a good time to lock in, and that went all the way back to the Great Depression. But even on the face of it, there will never be a time in the future when my mortgage will be as high as it is today. And ARMs always have a lower rate than anything you can lock in at today. So, if I can start paying down a bit more principal a bit faster today, then by the time that the rate increases, I'll have less principal than I would have had if I were locked in. Rates would have to not merely increase, but increase by enough to overtake the old locked-in rate by a significant amount (at least 0.25%, sometimes much more depending on how late in your contract it happens) in order for my principal to not be lower after the five-year contract period on ARM than fixed-rate.

      That's just the rough estimation method. The more cynical method is that band adjustors are not going to set their fixed rate contracts to lose money over the long term. Even though their marketing department promises that you'll be shielded from huge increases in rates, the reality is that they are fixed to rates that are not seen to be money-losers. I'm not educated enough in economics to bet against the bank, so it makes more sense to bet they're right and take the variable rate. According to that study I referred to earlier, this seems like the prudent path.

      Where the problem comes up is if you can't afford the fixed-rate payments, even when you're on an adjustable-rate. That is, if the rates do rise, can you swallow that difference? If you can't, you can't afford any mortgage. Period. You do have to understand what "adjustable" means. And that rates can never get down to zero, so when they're already damned near zero, they can only go up. This means your payments can only go up.
