I suspect that both the ionosphere work and Cyrus One's new tower probably played an impact on all of that stuff.

I think there are 2 dishes left on the light pole. I think they pulled everything off the monopole about the time they actually got the electric service ran. It was running off a portable generator for almost a year. On 9/1/2020 11:38 AM, Mike Hammett wrote: oh, wow, not even as a backup?

That 31-acre plot is just above the datacenter in the picture. The only thing they've used it for is that brick building with shrubs around it right at the street. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Nate Burke" <[email protected]> To: "AnimalFarm Microwave Users Group" <[email protected]> Sent: Tuesday, September 1, 2020 11:11:48 AM Subject: Re: [AFMUG] Ultra low latency PTP LOL 'Enough Money' These are traders we're talking about. They have bottomless pockets. They'll spend $100M on a project just to see if it works, then abandon it 6 months later. The tower owners we talk to hate these guys, they come in, spend a ton of money on buildouts, then just stop paying rent a few months down the way and abandon everything. They've learned to just charge a lot up front, and these guys will pay it.

But almost all of the HFT Guys in Chicago have switched over to the Ionosphere antennas. Where they have the huge yagi antennas with just a single licensed link back to the Datacenter. I can count 10 different sites within 15 miles that are using this setup. One of the towers we are on is in the process of installing a 3 antenna system, 30'x40' antennas at 100', 125' and 150'.
