We placed an order for new armored power cabling for Mockingbird Tower late last Tuesday (UPS three-day) with a new cable dealer who loudly advertises “same-day shipping.” They didn’t actually ship our order until Friday evening (without telling us)… so the cable, originally planned to arrive Monday (Tuesday at latest), still hasn’t shown up and we don’t know what time it will arrive.
This has forced us to postpone today’s tower upgrade to next Wednesday, the 25th. With luck, we’ll be able to dodge monsoon power outages for one extra week.
This Wednesday (7/18) around mid-day, we’re going to be upgrading the power supply and power cabling at Mockingbird Tower. We’re going to continue running on the existing cabling until we get everything laid out and ready to go, at which time we’ll cut over to the new power feed. If everything goes as planned, there will be no interruption in tower service at all; if it doesn’t, subscribers served directly by Mockingbird Tower might experience at most a two-minute outage as the tower resets. (No other subscribers will be affected by this maintenance.)
Part of the upgrade includes a battery backup system designed to be able to operate the tower for over an hour, to ride out any short-term monsoon-induced power outages that may affect Mockingbird Hill. In addition, relieving our power crunch on this tower should also help improve speeds to our Rio Vista tower subscribers.
This week our tower bandwidth improvement project is for all practical purposes complete. Read on to learn about the improvements we’ve made to our performance in Wickenburg and Morristown… plus a little bit of nostalgia in celebration of our 11th anniversary. Continue reading →
Since our last post, we’ve been hard at work on a new system to deliver more bandwidth to our four neighborhood towers in west Wickenburg, and to ramp our popular Mockingbird Tower up to the speeds necessary to support our increasing subscriber levels.
Subscribers of all our towers from Mockingbird Road westward may encounter some brief (5-20 minute) network interruptions this coming Wednesday at staggered times of the day, as we perform certain of the equipment upgrades described below.
Here are some details about what we’ve been doing, how far along we’ve gotten, and what we hope to accomplish Wednesday. Continue reading →
There’s about a 70% chance that we will have an opportunity this afternoon (Wednesday 1/31) to be able to perform an equipment upgrade at Diamondback Tower. Subscribers served by that tower may encounter several brief (about two minute) outages, along with possibly somewhat slower performance from the temporary mast we’ll be setting up to provide service while the original tower is being re-engineered. This work will affect only subscribers served by Diamondback Tower.
This week’s networking crisis is that black-hats have found another way to violate your privacy. Called the KRACK exploit, it allows hackers to spoof WiFi protocol so as to break its encryption and read your traffic.
It’s worth pointing out that this is not just a zero-day bug in some manufacturer’s implementation—it’s a defect in the WiFi standard itself, and all WiFi (802.11) encryption is vulnerable to it. It does require a hacker to be close enough to have physical access to your radio signal.
We wanted to let you know what we were doing about it, and also what you should be doing about it yourself. Continue reading →
As a result of a long-term project accomplished earlier this week, subscribers are now seeing faster speeds and improved response times. Most subscribers are experiencing sustained speeds exceeding their contract limits (some are seeing double their contract limit), with an additional speed boost layered on top whenever possible for brief, non-sustained transactions such as web surfing.

The battle continues on the Mockingbird speed issue.
In the past two days, our consultant pointed us towards two problems that allowed us to more than double the bandwidth capacity between our gateway and the Mockingbird Tower. Maddeningly, this increased bandwidth availability is still not making its way out to actual tower subscribers, and we are still at a loss as to why not. (Note that this is not happening on our other towers.) Our next step is to install some more sophisticated metering software at our gateway for our consultant to use to analyze traffic and routing issues within our network.
Today the new, faster, weatherized router model we’ve been awaiting (for months) to order, to replace the mid-2013 board currently operating Mockingbird Tower, finally hit US distributors’ shelves. We express-ordered one, which should arrive late on Friday. We plan to get it installed over the weekend, possibly solving our problem in whole or in part. (At the very worst, it will allow us to rule out a router hardware problem.) This installation will involve a brief outage, as cables have to be moved en masse from one unit to the other.
We wanted to let you know how the work is progressing, and that the Mockingbird speed issue is still our top priority… to the point where we have suspended all new subscriber installations to Mockingbird Tower until we have got it beat.
Thanks for your patience while we conquer this problem.
This announcement affects only subscribers of our towers located in Morristown and Wittmann. Subscribers of towers located in Wickenburg (including “postal Wickenburg”) will not be affected.
We are replacing the Network Operations Center router in Morristown with a faster and more powerful model. There will be a brief network interruption on the order of 10-30 minutes just after midnight Friday night (i.e., Saturday morning) to cut over power and cabling to the new router.
In a week or three, CenturyLink should be completing our recent order to double our gateway speed, resulting in our having more than three times the network bandwidth we had only one month ago.
Unfortunately for us, just having all this new speed available at the gateway doesn’t automatically make it accessible to all our subscribers.
For the past several weeks, a phrase has been looping through my mind from Larry Niven’s “A World Out of Time.” Tasked with a 200-year intergalactic voyage, the bulk of which he must spend in cryogenic stasis, the story’s hero is subjected to a rigorous dietary regimen to ensure his surviving the journey: before each cold-sleep session, it is crucial for him to “grow fat… and exercise to distribute the fat.”
This passage echoes in my head because it’s a perfect description of our current challenge. Continue reading →
