Brief Downtown Tower outage Tuesday

Recently, we determined that our Downtown Wickenburg Tower was exhibiting impaired performance depending on how long it was continuously operational. While awaiting the manufacturer’s diagnosis, we put a script in place to reboot this unit in the wee hours every four days, to keep it operating at peak.

The manufacturer replied today with the suggestion that reinitializing the unit from scratch should return it to proper operation. We’ll be performing this procedure around noon on Tuesday (tomorrow). This will result in a service outage of 10-15 minutes, which will affect only users directly served by Downtown Tower. We hope this will result in improved performance for our Downtown subscribers.

Morristown Tower East maintenance Wednesday

We’ve determined from subscriber feedback and subsequent testing that the east sector of Morristown Tower is not functioning properly and is delivering insufficient bandwidth. We’ll be replacing that unit Wednesday morning sometime between 9:15 and 10:30. ┬áThis will involve an outage of 10-15 minutes, that should affect only Morristown Tower subscribers east of the 267th Avenue alignment.

CenturyLink service interruption April 1

CenturyLink has informed us that they are likely to be disconnecting our network from the greater Internet temporarily between 3:00 and 6:00 AM on April 1. The interruption is to introduce new routing equipment at their premises and migrate some of their existing traffic to reduce load and reduce the likelihood of customer service interruptions. Service should resume no later than 6:00 AM.

This far in advance of the scheduled date, there is a good chance that CenturyLink may reschedule this interruption one or more times before it actually occurs. We will report any changes to the scheduled date and time as notice is received.

Update (April 1): Upgrade was achieved cleanly between 3:50 and 4:04 this morning.

Wednesday: interruptions for performance improvements

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

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.

CenturyLink Outage Plan

CenturyLink has informed us of a 15-minute service outage planned for next Wednesday (the 15th), sometime between midnight and 6 AM. This will affect all subscribers.

CenturyLink maintenance schedules typically change once or twice as the original announced date approaches. If this happens, we will publish a corrected posting.

Thank you for using Grand Avenue Broadband.

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
