SMB Internet market?
Can anyone recommend a good resource of metrics on the SMB Internet market? I am trying to find out which ISPs have the most market share and if they are using DSL, DS1, or Cable for access. Cheers Ryan

Hello Jimmy, I'm still seeing this behavior, which is causing a good amount of Teredo-based connectivity to fail.

We see ~ 180 mbps running over the relay so i doubt its a generic thing. Bye, Raymond.

Wacky Weekend: NERC to relax power grid frequency strictures
The North American Electric Reliability Council is planning to relax the standards for how closely power utilities must hold to 60.00Hz. Here's my absolute favorite quote of all time: Tweaking the power grid's frequency is expensive and takes a lot of effort, said Joe McClelland, head of electric reliability for the Federal Energy Regulatory Commission. Is anyone using the grid to keep track of time? McClelland said. Let's see if anyone complains if we eliminate it. http://hosted.ap.org/dynamic/stories/U/US_SCI_POWER_CLOCKS?SITE=APSECTION=HOMETEMPLATE=DEFAULT I believe the answer to that question is contained here: http://yarchive.net/car/rv/generator_synchronization.html [1] This is gonna be fun, no?

I don't see how this has anything to do with syncing two generators. The grid is in sync, and if the frequency of the grid changes (as it does all the time) it will stay in sync. It has nothing to do with the absolute frequency.
