Possible Diamondback work today

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.

The Wrenched Connection

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

West-side upgrades Wednesday 10/11

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.

251st Avenue tower outage Wednesday

Due to a recent real-estate transfer of the residence at which our 251st Avenue tower is located, we have been instructed to remove our tower.

We have already secured a commitment from a neighbor and long-time subscriber to assume the duties of neighborhood tower host, so we will be moving the tower to its new location during the day tomorrow (Wednesday). This will result in an outage of two to three hours for those subscribers and satellite towers served by 251st Avenue Tower, as the physical tower itself must be disconnected, detached, uprooted, transported, re-erected, cabled for power in its new location, and have its inter-tower feed links properly realigned.

After the relocation, we’ll be re-aiming the roof units of our closest-in subscribers first, then the farther-out subscribers as necessary. Our furthest-out subscribers in the vicinity of Circle City will likely require no re-aiming at all, though all signal levels will be compared before and after the relocation.

We apologize for this service interruption, and wish to assure you that we will be performing the relocation expeditiously, in order to resume service as promptly as possible.

“Big Sleep” to blanket Mockingbird tonight

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

Mockingbird testing progresses

Mockingbird TowerCondensed 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 Interruption

Subscribers homed to Mockingbird Tower (both Central and West) will experience a short interruption of service tomorrow (Tuesday) morning, as we rotate the mast down to replace the radio and pigtails for the Mockingbird Central antenna in order to attempt to alleviate our recent performance issues. We will also be correcting the tower’s cant at this time.

Should the problem turn out to be in the physical antenna itself (a much lower probability, but possible), time will be required to locate and ship a replacement for this unit, which appears to be in short supply due to a manufacturer merger. If this is the case, we’ll keep you informed via this blog.

Morristown: Brief outage today (Wed 4/19)

We’ve determined that the radio card on Morristown Tower West is souring, delivering unacceptable performance to subscribers, and requires replacement. We expect a replacement unit to arrive today, and the replacement activity to occur between 3-5 PM, requiring a brief service outage of around 15 minutes. The West AP serves Morristown subscribers west of the ADOT traffic sign on eastbound US 60 out to the end of Quiet Hills Road (except for subscribers in that area served by Skip-In Ranch Tower). Subscribers served by Morristown South and East APs will not be interrupted.
