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.
Each week, we get one or two “my Internet doesn’t work” calls from subscribers. Unless we’ve had a recent weather event (such as a wind or lightning storm), the cause is almost always never our network or equipment. Even more regrettable is when a subscriber calls to tell us their Internet has been down for a day or more, when simple remedial action by the subscriber could have restored service immediately.
Here’s a brief refresher on what to do before calling us for service: Continue reading
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
Subscribers served by Constellation Tower (this includes subscribers served by Diamondback, County Line, Black Mountain, and Easy Street Towers) will experience several short micro-outages around mid-day, as equipment and cables are swapped to upgrade Constellation Tower to gigabit bandwidths. The outages will affect almost all Wickenburg subscribers west of Burger King (except for those served directly by Mockingbird and Downtown Towers), and should last at most a minute or two; several micro-outages will occur before work is complete.
Watch for a posting later on this week in which we will discuss the infrastructure improvements we’ve been making over the past month to provide you faster service.
After last night’s testing, we suspect the most probable cause of the performance problem at Mockingbird is a bad customer roof unit radio hashing our tower. We’ve exhausted all the minimally invasive tests we can run. Starting tonight, we’re running a Big Sleep test on all our Mockingbird subscriber units. Continue reading
Condensed version: We’ve narrowed down the Mockingbird Tower problem to RF noise that spikes periodically. Our tower equipment and configuration are clean and validated. We now need to perform after-midnight testing over the next few days that will result in brief (10-20 minute) interruptions of service for a number of the subscribers on this tower.
Details and analysis follow for the technically curious. Continue reading
Mockingbird Tower subscribers (only) will experience a short service outage of 15-30 minutes this afternoon (Saturday), as the tower is being taken down for regrounding and recabling work to help address the RF issues causing poor performance from this tower.
After several abortive ordering attempts (in which “in stock” on a website listing apparently translated to “let us check our warehouse” once the order was placed), we located a dealer with a replacement antenna actually in stock. We have been verbally assured that our replacement unit shipped yesterday, and are awaiting written confirmation including a tracking number. In the absence of nasty surprises, we plan to be replacing the Mockingbird central antenna this weekend.
We are also going to be subjecting the Rio Vista antenna (same manufacturer and model) to testing to determine if it shows any early symptoms of the same failure mode, in case a prophylactic replacement is indicated.
Today’s status for Mockingbird Tower subscribers…
